I thought the staunchest defenders of the free market are of the opinion that America needs to be made great again.

I'm reasonably certain you've mixed up stereotypes. The staunchest defenders of the free market are keeping busy retreating back to the Democratic Party because it serves their interests more than the Republican Party does. They did the reverse in the 80s (hence "neoconservative") for the same reasons.

I'm... fairly certain that no one in this discussion realizes that's a Ron Swanson quote, or that /s means sarcasm.

anarcho-capitalists are trump supporters?

Oh that's a good point, I had just autocapitalized "Free Market™" (and tacked on that ™ symbol) in my brain reading the comment. I forgot that the words have actual meaning too. Yeah probably those guys are mostly holding their nose and backing Gary Johnson. :)
