In your view, there should be no need to nudge or wink. Let market have as it will.
You are misrepresenting my view. The reason for the nudge nudge wink wink is that the government, in allowing polluters to pollute, is acting against the interests of the people it's supposed to represent: it is allowing something that the people, if they were able to make the decision on their own in a free market, would not allow.
In other words, in an actual free market, a potential polluter would not be able to get any special favors from the government: they would have to get explicit permission from every person who would be affected. That's how a free market works: you want to build a factory that puts toxic chemicals in my groundwater? Sorry, no sale.
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.
