Those Satoshi’s bitcoin doesn’t seems like something that he lost, he might have actually just created a new wallet and throw those bitcoins there and then throw the keys away just to maybe add value to the circulating ones as he as he did say himself what lost coins are for. Or probably he is dead and no one knows the whereabout of the keys.
Even if we do not consider it as a lost coin, these coins are not in circulation. There are other possibilities too. He might let it remain in his wallet because he is a wealthy guy and does not need to spend his coins. Instead, he lets its users see how valuable it is today. Since people believe he has 1M Bitcoin, if they start to move, people will understand that Satoshi has almost 5% of the total supply.
If we look at the Lazslo cases it is because many people are just seeing it now as him been wasteful because of how expensive bitcoin is now, I bet before the mining of bitcoin even ends some of the next generation might even finds us stupid too for how we spent ours too.
Sometimes I feel like I shouldn't have spent the ETH that I received a couple of years ago as salary from a crypto project. I was getting 1 ETH every two weeks and I spent them instantly. It was around $125 back then.
