What would happen if banks and credit card companies started treating guns like porn?

I think this is the way forward on gun regulation. It wouldn't prevent every mass shooting, obviously. But there are a lot of losers who would struggle to acquire deadly weapons on impulse if they had to pay cash.

It's a backdoor way of keeping guns out of the hands of people with poor executive functioning, and one that does not interfere directly with either the right to bear arms or equal protection.
