no, a car for example devaluates over time.
The point is that "use BTC as a hedge against inflation" is obviously not a thing since people are chasing 10x growth.
If you buy a car and treat it like an investment (don't drive it, store it properly, keep it maintained) it behaves like an investment. Depending on the car and the market, the value goes up substantially.
Here's an example of a 2000 Honda Civic selling for $50,000 USD : https://bringatrailer.com/listing/2000-honda-civic-27/
Bitcoiners like to emphasize Bitcoin's limited supply, but Bitcoin is hardly the only thing in life with a limited supply. There will never be any more 2000 Honda Civics, for example.
The purchase price of that car would have been $27,320.28 in today's dollars. Also, you still have to store it and do some minor maintenance even though it's not being used. The true cost of ownership for 21 years isn't really known. It's hard to know how much the real profit actually was. Either way, it's a gamble as an investment strategy.
