Everyone will not use Bitcoin overnight. Progress is slow but gradually penetrates into every level. Don't think that Bitcoiners can control everything outside of the program.
From the emergence of mobile phones to smart phones, the entire process was not designed from the beginning. The author of the QR code never thought that the QR code could be used as money. Don't worry, life will find a way.
Well, we pay for coffee with Lightning, which is Bitcoin, so there is no point putting the miners and the energy costs here.
