My point is that they have plenty more bitcoin where the first batch came from; they can just keep going on and on. There's no point for them to not continue spending it, even if they are malinvesting, as they can't take it with them when they die, so why not establish an Earthly Kingdom that reigns in your stead, before you kick the bucket?
This is the economic malinvestment hell that monetary concentration brings.
If 20 million people have $100 dollars, then you can sell 20 million pairs of shoes. If one person has $200 million, he won't buy 20 million shoes. He'll buy two shoes to wear, and use the remainder to purchase all of the shoe factories, shut all but one of them down, and then make people whore themselves to him, to get some shoes. That makes him King of the Shoes.
A few people will be disagreeable enough to try to make their own shoes, and maybe one particularly rebellious shoe factory guy will refuse to sell and grumble in the dark, but the vast majority will just grimace, turn his tricks, and use his shoes.
