Dude makes 15 million a year, he doesn't set up anymore, he doesn't tear down, he doesn't help with merch anymore, he lets his crew handle it. Just like any artist making that kind of money, they have people doing that stuff for him now. the most strenous thing he has to do anymore is perform, which mostly consists of hitting play and adding a few effects to make it special along the way. there are far too many separate tracks involved for him to be recreating each track live like a band does. It's just not possible with the kind of music he makes. It'd be like Alex Gaskarth trying to play 4 instruments at once while singing.
