Regarding the infinite bitcoin-> sats pizza question..

Bitcoin = 21 million x 100 million
= 2.1 trillion max pieces

Dollars = 2.6 Trillion (USD in circulation) x 100 pennies
= 260 Trillion max pieces

If Bitcoin is ‘infinite’ because of the total sats is so many, USD is more than 100x more infinite! That’s not including the debt!
