This was thr original intent of thr Satoshi paper, except BTC is probably the worst payment network you can think about, which is why it failed to gain any use as such over the past 18 years…
Worst for whom?
Lack of chargeback risk seems nice for businesses.
I sent a transfer from the UAE to Spain and another one to the Netherlands. They took 5 days and 7 days respectively. The same transfer takes 10 minutes in Bitcoin. You don't do transfers to pay for stuff at the grocery store, the same way you would not pay using the Bitcoin network. You would use lightning network, which takes less than 2 seconds finality.
