I think the crutch now is not that it's hard to acquire bitcoins (thanks to coinbase and friends) or pay with bitcoin (thanks to stripe and friends), no, the only crutch is why should I buy bitcoins with my dollars when I can just pay with my dollars directly?
It can be useful for people who either don't have access to credit cards but have access to bitcoins, people who already have a lot of bitcoins and curious tech people.
