Lol it takes less to raise the arbitrary fiat limit of Bitcoin than USD. 21M (really 2 quadrillion 100 trillion units) was completely arbitrary, it doesn't even appear in the holy white paper. You have 6, now 5 core developers with write access to the centrally hosted Github. Nobody has or will consider any fork the real deal. But all of that is beside the point. USD can keep expanding at the rate it has since the Fed was established in 1913 and it will take 1,540 years for sats to become as scarce as cents.

Which part of this don't you understand: sats are 14 X more common than cents.
There are 14 X more sats after 15 years than there are cents after 110 years of the Fed printing.
They will never be as scarce as cents.
The psyop around 21M is that a BTC is a collective noun for 100,000,000 units, not 100. The current limit on sats is 2100 trillion. The current number of cents in circulation is 150 trillion, cents are 14X more scarce than sats.
You're comparison is completely out of touch. There are 632+ trillion alone sitting in derivatives currently. Compare Bitcoin to the global total wealth including stocks, derivatives, real estate, cash, collectibles and so on because that will all be demonetized by Bitcoin.
Hahahahahahahahahaaaaaaa there go the goalposts
