A little context missing in your post : Lazlo was between the first hundred ( number could be inaccurate anyway ) contributors to bitcoin project and one of the few active developers. SO on one hand I guess he owned way more than those 10000 and also he made the history  proving the world Bitcoin could be used as a means of payment and wasn't only a computers's geeks experiment for its own sake.


So now ask yourself : how'd you feel being among the first discovering bitcoin. Well, I would feel quite comfortable tbh.

 

@OP, hopenotlate is right in what he said, if Lazlo said he doesn't regret spending 10,000 BTC for 2 pizza, what do you have to fight against it? His involvement into Bitcoin is quite early and you can assume that he doesn't just have that amount of Bitcoin that was spent on pizza, he is the reason why there's Bitcoin pizza day, which means his contribution is greatly recognized by the Bitcoin community.

I’m the man that always wants to move forward on my previous mistakes. I will feel a bit regretful but that’s it because I can’t change the future.

We don’t need to discuss things that will make as sad rather we should view it as a first successful transaction using Bitcoin as payment to goods.

Lazlo is our hero for taking the first step on using Bitcoin as payment despite it cost him a lot of Bitcoin at that time.

Likely accept his expression as simple as that and if you understand the the yoke (setback) Laszlo Hanyecz has broken at the effect of his paying 10K bitcoin for 2 pizza's as the case maybe, he was the first enthusiast that executed the ultimate use of bitcoin for alternative means of payment, you'll appreciate him for the libration of bitcoin which had now earned global and a massive trading volume even among the top notch of global assets today, you'll celebrate him for that instead of the mockery.
And if we keep to live by such criticism, then we should not have to sell our coins anymore not until bitcoin has reached it maximum volume where it can't increase again and i bet that's not going to happen now and not yet neither would it happen soon or even.

So we just have to keep holding seeing Aths after Aths like we're just holding an illusionary values. Huh? Is that what is expected? I bet not. So even if we've to sell out bitcoin today probably when it was $10 or below to this day we've seen an Ath of $111,000, there's sure that the peak could just be the begining because more Aths is expected to come not just in the close time of this current bull run event but in most potential places as the future goes.
However, he had set a historical experience for us which is the bottom (first approach) where paying for goods and services with bitcoin started.

If I was the one who bought 2 pizzas for 10,000 BTC, I would not regret it, seeing the way I am being celebrated every year and the impact that single transaction, done many years ago, has had on the Bitcoin community. That single transaction is an inspiration to me and many other Bitcoiners who are amazed by such a moment in history.

Today, we have a double celebration. Congraìtulations to all those whose investment goal was to hit 110k and take profits. It will be very tricky for those who have such an investment goal to take profits at 110k when Bitcoin has the prospect of going beyond the current price of 111k. The rule for every investor should be to stick to their investment plan in order to avoid missing out.

It is easy to say about it when you are not the person in this story because you did not spend bitcoin for any pizza when it was cheap and years later it worth 100k-fold more expensive.

I agree that if I have had a lot of bitcoin, more than 10k bitcoins, I would have not feel regret by my spending of 10k bitcoins for 2 pizzas years ago. Especially if I did reserved my remaining bitcoins for years later, I would not consider that trade as my bad decision at all.

Assume I had 1 bitcoin in 2018 and spent 0.1 bitcoin for anything in that year but I managed to hold remaining 0.9 bitcoin till 2025, I would feel good enough without any regret, to be honest.

I can't really say how I'm going to feel if I was the person but I know that the person who gave out that 10, 000 BTC for 2 boxes of pizza will be regretting by now knowing the current price of Bitcoin but on a second thought, do you really think the person had just 10, 000 Bitcoin? If he gave out all that he had in his portfolio by now he would be wishing he never bought that pizza.

Even if he didn't buy pizzas with the bitcoins, he would still have spent those bitcoins before we got to the current price. Bitcoin was literally worth less then. Certainly, apart from Laszlo, there were other early Bitcoiners who had that much Bitcoin but spent theirs as well. Laszlo's yearly recognition is still a good compensation for spending his Bitcoin.

We all won't hold our bitcoins forever, one day we will sell them off, and Bitcoin's price will keep surging on. Are we going to live in regret forever after spending our bitcoins? Like I said before, if I were Laszlo, I would have no regrets. I would rather be proud of being one of the early men who adopted Bitcoin and set the pace for others to follow.

Of course the Bitcoin community widely recognizes his contribution because his transaction was historic even to my knowledge this active developer was the first to use Bitcoin commercially. Besides he was a miner, so the value of those bitcoins probably wasn't very high for him. 15 years after his pizza purchase, Bitcoin has already surpassed Amazon in terms of market capitalization, and Bitcoin has currently touched $111k so now it is proven that his 2  pizza is currently worth billions of dollars.

It must be said that today is an important day for us because Bitcoin has reached an all-time high and Bitcoin Pizza Day has turned 15. At that time the value of Bitcoin was literally low, but now many are following him because of his noble work.

Both of these are the best idea today and they are also related to each other which is why it is very happy to see them both and their meeting like this indicate luck and a big investment. If he remember that I made this mistake then he must still be feel wrong today because he made a very big mistake and if we look he did it in a good way at that time because he did not know that the price of BTC would go so high. That is because you did not make this mistake and if you had who know what you would have done.

If I were in his place I would think every day about how to become rich now because why regret what has passed. Rather I should work hard from now on make myself strong and achieve success by earn BTC.
