Once you understand Bitcoin, there's no way why you'd go back to the legacy system. It's not Bitcoiners getting freaking rich; it's them adopting a superior store of value that is being selected as the winner in a free market.
Most people are perfectly happy entrusting their (fiat) money with the banks, and asking permission for accessing their funds. Bitcoiners, on the other hand, have tasted the freedom of self-custody and a permissionless payment system.
Whether it has value or not depends on how important it is to have a monetary good that is not issued by a nation state, and cannot be controlled/stopped/inflated/modified.
