all of those things are fine and good, but they aren't something you can easily put your savings into - you have to save up to buy most of that stuff, and you can't just horde physical items without necessary storage and protection. Further for some people these things all pose substantially more risk than bitcoin. If someone burns your sheds down or salts your farmland because you can't payoff the local rebels, you risk losing everything, with bitcoin, having poor timing on exiting the market is risky, but certainly not 100% wealth loss risk and that's without even considering the aspect that memorizing a wallets secret phrase is the only upkeep you need to hold bitcoin. All of those physical assets bear some form of time/energy to maintain/upkeep and as you mention have a strong downside of making you immobile.

I'm not saying everyone should store their savings in bitcoin, but I am saying it serves a very real, potentially life changing purpose for some people and that shouldn't be discounted.
