That proves the point. To be able to fold a simple protein, you have to be capable of simulating the very challenging simulation of "real world physics at an atomic scale". To simulate a brain, you get to do that for a few hundred trillion proteins that make up a brain...and all their interactions with all the other trillion proteins. The complexity doesn't come from the proteins so much as the physics that govern the proteins.
