The way I look at mistakes are UTXOs with lost keys.   They will just pile up.

The unit of bitcoin is anUTXO, not a sat.   Sat is just a denomination but they can’t really be moved - a UTXO is required for the “movement” of any sats.

There is a very small number of UTXOs relative to the pooulation of the world and hard limits on the creation of new o es and the exchange rates of current ones - this is what has so many panties in a bundle.

Cool question.
