Just to clarify:
I'm not against the digital gold concept. I'm only against the conception that Bitcoin should be treated
only as an investment now and not as cash. It can and should of course be a store of value too!
Good one, I am glad that finally someone is talking about this because for years now I feel stupid telling people repeatedly that you lose nothing if you sell your Bitcoin and buy back at the right time.
That's not what the thread is about

It is about spending Bitcoin to pay for goods or services, not to sell it for fiat. When you re-buy, if instantly or if you try to catch a dip -- there can be different strategies associated with risk.
This is as much bullshit as pretending to create jobs by having people digging ditches and then covering them up to dig them again, etc.
It can be compared if the work of these people has some positive effect, for example strengthening their muscles
I've already written in the OP that the reason to spend Bitcoin and then re-buy is to strengthen the circulation. The main goal is to incentive merchants to accept Bitcoin. AFAIK there has been a bit of a decrease lately of shops who accept Bitcoin or even other cryptocurrencies (in my country there are only few left), and this is not a coincidence as people aren't using this feature that much.
Circulation strenghtens Bitcoin in various ways. If it's widely used for payments it can stop downward volatility a bit, as it increases liquidity. It also can lead to a perception as a unit of account if merchants begin to use Bitcoin prices for some goods. This effect would be at first only temporary - when Bitcoin moves sideways - but then could get stronger over time. And third, the argument of many Bitcoin critics that "it's only used to gamble/speculate" would be refuted, which has also psychological effects and should be great for the price evolution (and thus also for the "digital gold" camp).

I am one of those who thinks bitcoin is digital gold but that doesn't mean I refrain from making any transactions and I don't think Lazlo was wrong by any stretch of the imagination.
I was maybe (on purpose

) a bit too generalistic about the "digital gold camp". There are of course a lot of people like you who like the "store of value" concept but don't disagree with the usefulness as payment means either. But I'm a bit tired of those who think that Bitcoin can now "only" exist as an investment and the cash feature is somewhat outdated.
My personal definition is that Bitcoin has some similarity to gold silver coins, i.e. it is "hard" but at the same time useful for paying/spending. (Yes, gold/silver coins are currently not used much for that use case, but cash was their original purpose. I know, Gresham's Law is working here, both in the case of Bitcoin and with gold coins. But the possibility to almost instantly re-buy Bitcoins makes it somewhat easier to circumvent Gresham's law in the way I laid out in the OP - in reality, you're spending fiat, but using Bitcoin to make it circulate).
Anything outside the Bitcoin blockchain (wrapped BTC, Lightning Network, intermediaries, etc.) is not Bitcoin - you might as well use PayPal.
In the fiat world we have also prepaid cards, digital wallets (Paypal!) and similar tools where you temporarily transfer your money to a less-safe platform than your bank account (which could be seen as "pure fiat") and use them for easier, more private, or cheaper payments. Liquid and similar platforms can be compared with that. In the case of LN I disagree because you are dealing with pure Bitcoin UTXOs which are bundled. But I won't deepen this discussion in this thread, there are many LN threads for that.
In addition, the "circulation" effects I mentioned in the answer to Free Market Capitalist also applies in the case of second layers.
Currently, central banks offer cheaper, faster, and more private transactions than Bitcoin, with bank-to-bank fees under $5, depending on the bank, country, etc. but I'm not going to compare all banks here, overall, it's cheaper and faster.
Normally if you're not in an absolute hurry you pay currently less than $1 for a transfer even on Bitcoin mainchain. And international bank transfers are much more expensive, I have to pay 30-35 dollars approximately for such a transfer. You could use PayPal, but again, that is like using Liquid with Bitcoin
