Thing is, giant mansions existed in the 19th century too. They would’ve already been affecting the average home size in the 20th century.

The growth AFAIK is largely driven by the suburban mcmansions, which aren’t necessarily a 1% thing.

Well only central banks can create it out of thin air. Normal banks lend other people’s money (fractional reserve banking)

That would be the difference between a permissioned ledger vs a decentralised cryptocurrency. Pretty hard(not impossible) to turn off someone’s bitcoin, but depending on the design, the state backed crypto might be very easy… Or not.
