First off, you're hand waving over every person who has ever used bitcoin to purchase anything, which is a lot of people buying a lot of stuff.

When I started mining bitcoin no one was talking about it every have a USD value. It was just silly internet points that you could pass around to friends. I also know a lot of people who hold as a store of value believing that it will easily outlast the US dollar.

Just because all your friends are clowns doesn't mean that those are the only people that exist.
