His methods aren't insane. They're rational for survival in human society/civilization without participating in it.
Think of a rat or other mammal pest. They effectively survive off of civilization in the same way.
And since he got away with it for the entire time...successfully...it seemed effective, too.

Living fully alone isolated from civilization in terrain as hostile as wild alaska isn't realistic. See Christopher Mccandless. It's simpler to just scrounge off of civilization.
He started out well, but about halfway through meandered into bullshit. Bad data, cherry picked data, incorrect incorrect understanding of the science, incorrect conclusions -- he even referenced the Cultural Marxism Conspiracy theory: https://en.wikipedia.org/wiki/Frankfurt_School#Cultural_Marx...
By the time we hit "why we're blind" he's gone fully off the rails.
I sympathize with him -- and even agree with several points, but he did himself a huge disservice here.
