Primary residence has utility. Additional properties typically have a real cash flow. Stocks have price appreciation typically due to higher current and projected earnings, dividends, and buybacks, and yes they are somewhat inflation resistant since they also have limited supply. This makes for average returns of 10% plus dividends.
Bitcoin is a collectible. It is very much like gold, which has a far longer history and similarly high transaction costs. Gold, in my view, is also a collectable, and it's frequently advertised as such. (Just look at the gold coin ads and compare to BTC.)
Controversial view: fiat currencies are also a collectible. The difference being it's universally accepted tender, its government enforced, you're taxed in it, transaction costs are cheap, and insanely fast (moving money can be a pain). This is what makes fiat a proper currency. Also, while we like to make fun of central banks for money printer go brr, there's real value in the stability they provide. The Great Depression was a disaster because of the lack of monetary response, and banks of the world have learned since.
Also, there are heavy incentives for governments to drive use of their currencies, and there's a LOT of competition from governments to dethrone USD. China, for one, is trying to internationalize the renmimbi and dethrone USD in its sphere of influence. Do you really think they're going to give BTC the space to thrive?
Now, let me be clear, my view on crypto is nuanced--I'm very exited about DeFi and ETH2, but my longterm view on BTC is a bit sober.
