So in your view a free market has perfect actors with perfect information
Where did I say that? You don't need perfect information; you just need the freedom to act on whatever information you have, combined with your judgment about what's important.
none of them think "climate change" is a hoax?
A free market also means we all get to exercise our own judgment, instead of having the government exercise judgment for us.
This is not reality my misrepresentation of your view was better than this one. :(
