I have faced the same problems both in paying others and wanting to be paid by others and I have to say this has nothing to do with "industry maturing" or anything, the problem you are facing is with the other party and their unwillingness to accept the payment method you are offering them.
for example PayPal has been around for many years and it is mature but if you were to offer PayPal to many people around the world they will not accept it because they don't want to and you can't change that not with time nor with anything else.
