What is so great about Anarcho capitalism?

I cant see what is so good about zero regulations when human greed knows no bounds.
(Maybe i don’t understand what anarcho capitalism is really about? If so please correct me)

And another question; Why do i see so many climate change deniers on here? There is endless evidence for climate change.

Edit: to be clear i am not a socialist, i am pro free market capitalism (with regulations of course)
