I don't think it's either practical nor feasible nor even desirable to use Bitcoin in the day to day dabble of pizzas, phone credits, hairspray and sneakers. People try to, because of the misguided belief that Bitcoin value is somehow related to or deriving from its crossection in the retail market. This happens to be completely untrue : you can't buy any pizza with SDRs, and yet that doesn't somehow make SDRs worthless. The belief itself may be a case of "everything appears a nail to the man holding a hammer", in the sense that people who have never interracted with any other aspect of economy besides the supermarket counter may genuinely imagine that's what economy is. Still, that makes no difference.
