Kind of hard to convince people when it is a huge pain in the ass to even buy them.   And the greed around the scene has gotten out of hand.   ATM owners charging 8 percent commission, jumping through hoops to try to buy on an exchange or meeting some freak in an alley in a local buy.  Until they are easily accessible why would any normal person want to use them on a regular basis?   Hard to get, so of course when you get them you are going to hold on to them not use them.
