I just want to go with whichever chain allows me to buy a coffee now...and when I am an old man looking back 50 years from now I can point to that transaction and say "that was my transaction...it was a coffee and it was delicious".
Why not just use physical silver and then you don't have to worry about all your transactions being tracked and monitored in an Orwellian-style dystopia?
Because nobody accepts your dumb metal as payment. And cameras are a thing.
