Capitalism works best without the laws (not all but most of them). Capitalism relies on the fact that producers and consumers are free to choose whatever the best options presented to them. The market should make the decisions, not the government.

Would capitalism work better if people were free to smoke crack?

Would it work better if people could choose not to educate their children and instead spend the money on other things?

Can you enumerate which current laws capitalism would be better off without?

Occupational licensing laws, for starters. Even the Obama administration agreed: https://obamawhitehouse.archives.gov/the-press-office/2016/0...

You think competition law is needless nonsense? That a pure free market does not end up with a handful of people owning all of the marbles?

Or without factories full of workers burning down, or without pollutants getting dumped into streams, or without company towns locking workers down into slavery-in-all-but-name, etc., etc.
