I believe this is exactly what cryptocurrency was made to solve, to prevent legitimate businesses from losing a major revenue stream at the behest of a select few payment processing companies.
It doesn’t help that the major players in payment processing seem to often work in lockstep, being banned on one platform often leads to being banned on another.
While I recognise cryptocurrencies are far from a perfect solution, short of legislation, which is even less of a perfect solution, cryptocurrencies democratise payment in the digital sphere, free of institutionalised, arbitrary gate keepers.
