Yes they would, but in reality it’s anti libertarian like completely free market capitalism,. which is shown not to work, so how anybody takes it seriously IDK?
Capitalism is ALWAYS regulated, but not always with consideration to consumers and environment. Social democrat societies like Scandinavia are generally considered among the best. But even more “free” capitalism oriented countries like USA have regulations.
But you can’t have societies without regulation, the whole idea is moronic. The difference is whether it’s good as in beneficial regulation, and what it attempts to benefit, Profits or citizens and environment.
