They compared it to the appreciation of real estate, which is wildly divorced from real value. Real-estate prices in say, the Bay Area are driven by legislation and speculation. Not actual value. The move to remote works accelerates the discrepancy.
Isn't the value of a house what someone is willing to pay for it? There are still a lot of people buying homes in the Bay Area to live in. There are just a lot of rich people in the area, so they're willing to pay the price that the market is setting.
This is why it's being compared to crypto currency. The parent comment I was responding to said it's not a fair comparison but "it's worth what someone is willing to pay for it" describes both.
