I know PA has auctioned off a game DMed by Chris Perkins for Child's Play and it's sold for a ton.It's... not a terrible idea? Lots of people love of the game, but don't have the necessary skills to actually DM a game. People who can run GREAT campaigns are few and far between. People -will- support that shit, or we wouldn't have stuff like HyperRPG, Critical Role, and such. And I'm betting Matthew Mercer could charge thousands of dollars for a campaign and some folks WOULD pay it.
That said, I think anyone has the skills to DM. It's more about courage to step up.
