He's not even doing this because he needs the money. That would still be stupid, but semi-understandeable if he was broke and needed dough. That seems to leave notoriety as the only reason to do it. The opposite of what he needs.
I still submit that he should go live in BFE and work at the local hardware store or something and live a low key life. As others here have pointed out though, maybe the whole Martin ordeal just totally messed up his brain.
