I think he'd do fine; he drives to a grocery store in one of his videos. The only question for me would be housing. If he wasn't provided a place to live, I could see that precipitating a crisis, but as long as he has a lair he can hole up in he'll probably continue on mostly as he has for the last twenty years. Because Kentucky isn't too tight a real estate market, I would bet on him being able to afford a trailer long-term via tugboat as long as some kindly relative handles the procedural side of things for him.I know we talk about "What happens when Barb dies" a grip but this is a way more interesting one. Does he finally leave the house? Does he starve to death? Could he even get food by himself (if his problems are that severe)? Can his beady little eyes adjust to natural light? I am honestly curious.
While we get an intensely exceptional side of him in his basement tapes, in videos where he is interacting with his family he just seems like the kind of crazy that a lot of families have one or more of around. In public I don't think he's flinging shit or attacking people, just acting hella bizarre in terms of voice volume, mannerisms and the things he says.
He walks around the neighborhood at night sometimes. My sense is that Baugh is considered a local eccentric-- I'm sure he creeps many people out but I think he's reasonably high-functioning, just super fucking weird (and twisted by anger/isolation).
