Automated road tolling systems have the exact same economic problems as Patreon. And the pre-charged wallet with $xx minimum fillups is exactly the model they chose. Judging by the longevity of their systems, it seems to work fine.
as was mentioned below, you don't really have a choice with road tolling systems. i don't like having to pre-load $xx, but it's better then the only alternative. people can stop interacting with Patreon, but you can't really avoid toll roads very easily.
At least in the Illinois Tollway you do: pay more by stopping at each toll.
That's sort of the same thing here, right? Prefill a wallet and you don't have to pay extra for processing fees (equating to convenience going back to tollways).
