Voting with your money on its own rarely accomplishes much unless it is an overwhelming majority vote. There are also a huge number of things that simply cannot be managed properly, to the overall benefit of society, by demand-side market forces. There is a time and place for regulation, carefully considered and designed, with a change/revision process in place.

A big problem with lawmaking systems in the USA at all levels of government is that the change/revision process is virtually nonexistent. Laws are not adjusted as requirements change and understanding shifts. Regulation is hard in that environment, but the optimal amount of it is certainly much greater than "none at all".

It's simply not possible to maintain a functioning society without regulations on at least some things at least some of the time. Anti-regulation dogma is just propaganda by rich people who would become richer if their preferred bad behavior wasn't prohibited by regulation.
