Are you sure it "certainly" doesn't hold for cars? Cars are expensive as hell: after the amortized sticker price, maintenance, gas, parking (I pay $150/month to park near downtown Seattle) and insurance, it takes quite a few Uber rides before choosing the renting economy puts you in the red overall. And by contrast with a house, a car really isn't any household wealth worth speaking of, they depreciate so fast.

If cars had a delivery system as efficient as netflix, it would make far less sense to own a car. Longer-term "capital" goods are very different than disposable media consumption - some like cars (and media, and technology) deprecate but land is an investment in a commodity that is getting more in demand over time.

It's especially true for cars. Uber style car renting brings a much higher utilization for them, and the costs of car ownership are almost all in capital and fixed ones.

Isn’t it especially true for cars and houses? You need a substantial amount of capital for both of those, especially for a mortgage. And that’s not even getting into whether you actually own something if the bank can take it from you for missed payments.
