I'm from the USA, and I voted against.
Regulations are most often created to do one of two things:
1) protect the public from unscrupulous actors
2) protect entrenched interest
So it depends. Regulations written by lobbyists to promote a specific agenda should never exist, but they do. Many core regulations like "a real estate agent needs a license" are important to protect the public.
I think these "protect you from yourself" regulations are paternalistic. For example with real estate agents: if I can buy and sell a house completely on my own, why shouldn't I be allowed to pick my own middleman? It even feels somewhat insulting, to think that I can't just look for an agent with good reviews on the web, or trust a friend who got a good price on his own house. Did you know that the average real estate agent lists their own homes for longer than they list their clients' homes?
As for Bitcoin, I think it solves the problem of people who think they're helping, so they use violence to enforce what they think is the right decision. There's so much power behind money that the ability to control it all will always fall into the wrong hands.
So like realators, I'd rather see the truly clueless get burned and lose their money, than see mature adults told who they should and should not be allowed to trust. Any democratic government can never be smarter than the average voter, so democratic paternalism cannot be justified.
