Good question, and the answer is quite simple. You can’t eat a Bitcoin, can’t wear it, live in it or enjoy experiences with it. People will buy stuff once they need it or feel like it’s worth it for them

Sure. But if bitcoin is the defacto currency then they can just put enough into circulation to make the bit of BTC they spend to be massively expensive and pay for whatever they need, while still having enough to do massive projects that they want to do (or not). Could also die and have the coins locked forever.
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.
