Oddbean new post about login | logout and frankly man you're still measuring in USD when you translate the price (in USD) of a house or car into bitcoin. still fiat denominated. this continues until it is an actual UoA and MoE. that is to say, that prices are set in BTC.
I've been measuring RE, used cars, my salary, these days groceries too in bitcoin for years. You're welcome to wait your turn to switch denominators for that (again arbitrary) time in your head when it makes sense to switch, but it's a major life hack you're waiting to take advantage of. Patience is a virtue
