Realistically, it takes years for Bitcoin to protect purchasing power, not minutes or days. People who bought Bitcoin at $66k in 2021 haven't protected their purchasing power at all over a 3 year period.

It is a two way street. Monero doesn't fix the money issue, but it does address privacy, censorship and cheap transactions.

Bitcoin fixes money, but presently has no working solution that can scale and address private and cheap transactions.

Any relegation of these requirements to fiat standards defeats the purpose. Monero is no more complicated than Bitcoin.
