Just to my monkey mind the limitation to every legacy currency has been fungibility. On the big side is settlement and on the small side is decimals or fractions. On chain 2.1 Quadrillion is a no more than number and it's enough for micro transactions. SETTLEMENT is the bar tab and your reputation with the people you are engaged with.

With lightning the 2.1 quintillion maximum makes the bar tabs even easier to settle.

Sure the price of tomorrow may be zero and maybe it already is as the exact amount of money has always been the same from the beginning of time to now. The difference is that the ledger has been arbitrary and backed by violence or just attention.

Now we are at the point where attention is the currency and BITCOIN is the denominator for those who relish in the central planning and those who relish in liberty.
