Part of the headache here is that this situation inherently props up a few monopolistic platforms, rather than allowing people to use whatever payment system is available in their own countries. Some of this can be worked around using cryptocurrencies – famously, the Mitra project leverages Monero for this very purpose, although I’m told it now can accept other forms of payment as well.

Hell yeah, I didn’t know about Mitra. It sounds like it’s a Patreon esque kind of deal.
