Yes, but by limiting spending they limit the amount of stuff/influence they can buy. The point is, once you spend it, you can’t create more unless you provide value to others. To your second point: that would be awesome. Let’s say I own a million bitcoin. If I die and don’t pass it on, this means that these 1 million bitcoin will never be sold on the market again. It’s basically a donation to everyone else that holds Bitcoin, as contrary as it may sound.
