On Patreon you can choose any combination of either in any number of tiers. And it works. Both creators and consumers get the flexibility they want. It actually kind of functions like a market.
Now, I'm not saying Patreon is perfect. For example, the fact that it is The One Big Player in this arena is a problem, because "walled garden" style markets are lock-in issues waiting to happen. Still, this is one thing it definitely got right.
Why YT would not be technically capable of the same, given the budget available to them, is beyond me, so I can only explain this as a choice on their end.
