I agree there’s something to be said for this — If you have a above-board business that credit card companies don’t want to service because they think it makes them look bad, that should not shut you out of electronic payments yet that’s basically where we are at least in the US.
This is a little hard to balance with the fact that the same things that let you circumvent gatekeepers like credit card companies also make it attractive for genuinely immoral things, but that’s a trade-off. Every currency can be used for immoral things and just because cryptocurrency might make it a little easier doesn’t mean it’s inherently immoral.
