If you don't want to do it, you will find a million ways and excuses to not do it. Those who want or need it will find a way, and such ways have existed for over a decade.

Existing for over a decade is not a stamp of quality, usefulness or convenience, but it is true that it is available, and people are free to use it should they want.

It does not solve the issue discussed here though, as being able to get a money in a intermediate currency from A to B would only be handle a small part of payment processing and operating a business, and does not solve that you're dealing with groups that use any means available to put you out of business due to finding your business immoral according to their beliefs.
