Which, as we know, he won't actually do. The moment he was actually obliged to do anything to earn that money, it would become work, and he simply refuses to work.
If he were a little smarter and a little more honest, he'd just set his Patreon to "tip jar" mode. No tiers, no rewards, just donate what you want to help support him. But since all his "friends" do reward tiers, he has to do reward tiers, and I also think on some level he knows perfectly well that no one actually wants to pay him just to be him. (Which is part of why he's so angry all the time, he really believes he deserves to be paid just for being him.)
