I’m not sure “pay what you want” will really work for most people
But I do think the following all work:
Pay something so I can keep making stuff (Eg patreon, kickstarter)
Pay for VIP access (Eg private streams)
Pay for real-time access (Eg super chats)
Pay for early access to new stuff (Eg memberships)
Pay for a physical item (eg overpriced merchandise)
