If we look at Bitcoin's original purpose was to replace traditional payments that existed from the beginning that lacked powerful technology, Bitcoin was indeed designed for a payment instrument with more sophisticated, more transparent and of course decentralized technology.
But all of that has now turned into Bitcoin as a long-term investment for community trading, this is also because of the regulations that are applied to each country that govern all the rules about the use of Bitcoin.

So when someone spends their Bitcoin on something they want to have, it's a thing that doesn't violate Bitcoin's initial rules, it's a goal that's actually achieved at the moment.

Being able to control your crypto coin is totally yours without the least bit of regret. Deciding to withdraw your balance in order to enjoy the rewards of your effort is totally your right and should be respected. Having your coins as a mean of preserving money is just as important as using them to have fun.

Having strategy of holding coins is completely sane in terms of increasing your finances in the event of price increases. Splitting your savings through withdrawal has been shown to lower the psychological effect on you when transacting. You will always have total control over how your finance work out.

Not about replacing in the true sense, but in the Bitcoin Whitepaper explanation, it reads about "without going through financial institutions and replacing the trust system" not to replace or eliminate the banks or Fiat currencies that are currently in use.
And it's also about the freedom of ownership because the concept of peer to peer does provide a goal for full options aimed at the user himself.

And as time goes by and technology develops, Bitcoin is now turning into a Global Reverse Asset or Digital GOLD and also as a cross-border payment and becoming a Complementary Asset by becoming an institutional investment instrument with ETF products.

Yes, that doesn't violate the purpose of bitcoin and it doesn't have any rule that we should spend it. And that's why I will not say anything or blame someone whatever they do with it. We already have seen how it's being utilized for different use, as a store of value or an asset and then as a means of medium. All of it works in the same way as is, and there is no need to redirect them on how it should be used.

There's no need to be specific about a strategy for holding because it's as simple as it is.

That is true everyone have a decision to make concerning how they want to use their Bitcoin, personally I will prefer a situation where I can hold my Bitcoin for a long time as a store of value, why people are holding Bitcoin as a store of value is because they want to make one profit or the other on their Bitcoin investment which I think it’s a good way of approaching bitcoin for the long term benefit and gains. There are people who also get involved and in buying and spending bitcoin which I think it’s also a good process and thinking ahead of time on how to strategize their investment plans to also have a desired outcome for the long term. The plans is always to buy and accumulate bitcoin for a long term which will also enable us have profits when the market starts growing and probably when you’ve gotten to our 1-2 circles then we can decide to sell our profit.

And that's why Bitcoin is decentralized, not regulated by anyone, without being controlled by a single central authority such as a bank or government.

Whether you want to spend it or want to make it a long-term investment is a personal right,
this is like having your own bank that you can manage as you want without third party intervention on the condition of using a non-custodial/self-custody wallet.

This is a Brilliant Idea, if implemented vastly, it may have its own positive impact on the adoption of Bitcoin in a way too, But just like you have rightly said, the challenge of more faster and reliable payment processors will and still is one of the biggest challenge we will be having with this, and mind you, Bitcoin is in limited supply, so if it should be used vastly as an every day means of payment, it may get even more expensive not everyone will be able to use it since they cant afford it, although it isn't a significant challenge enough, but just taught to mention it. As for market places, there are some out there where you can spend your Bitcoin, there are countries where it is considered a legal tender, it is accepted in stores across such countries and there ae also establishments where they consider it as a payment option, with such establishment, you can go ahead to making your payment in Bitcoin.

Hmm, OP, you have a good point, but you know the reason already. Most BTC holders already know the good money and bad money concept. Because when you have something that you expect to be worth more in the future, you spend the one that will lose its purchasing power, which is fiat. But we can definitely overcome this mindset by securing our future through other sources of income or the businesses we are running, so we won't care if it goes to $1 million or not. But we still want to be in, so most of these spenders have already saved some of their coins for the long term and spend the rest of the earnings they earn in BTC.

Also, the places where we can spend our bitcoins are very few. Although where I am now, they are introducing laws and tightening everything, those are for better settlements for us so scam rates can be reduced. Although there are several other things that a merchant and a user need to know, as you said, they have to get that knowledge because it's not that hard.

BTC can easily become the MoE when the spending side is as easy as the earning side. Until then, SoV is going to lead.

In my opinion, how people chose to spend their bitcoin should not be anybody’s business.  It’s already obvious that people are coming into bitcoin for profit because, they see it as an opportunity to make money but doesn’t mean everyone has to share the same goal.  There are people who want to hold it for the long term, some want to be spending it and others simply value the financial freedom it offers.  Even if we introduce these things you just mentioned, it won’t change anything people will still do what they want with their bitcoins and there is nothing you or anyone can do to control them.

Spending ones Bitcoin is not actually wrong but this actually depends on your position or status in Bitcoin investing. Someone who newly invest in Bitcoin is not expected to begin to spend it from that moment, and when no profit has been made out of your investment. To spend your Bitcoin, it is advisable to do that when your Bitcoin investment must have grown, and probably you it is matured enough to be sold after the Bitcoin market must have experienced bull season. Also, one can equally spend his Bitcoin that you are not ready to invest and keep for long term. For instance, some of us uses Bitcoin for various transactions, sending to someone, use it on betting platforms, and many other things, but in most cases we do it out of the profit we have made from our Bitcoin investment.
