real world application: moneyIt certainly matters what the broader population thinks if your aim is mass adoption. It also matters if your goal is passing legislation for a Strategic Bitcoin Reserve, which becomes increasingly unlikely if Bitcoin is politically tied to Trump.
Why would gold go to zero even if Bitcoin continues to appreciate indefinitely? That makes absolutely no sense. People would be buying up gold to turn into jewelry long before its value ever reached zero. Conversely, there is literally no floor underneath the price of Bitcoin or any other crypto, since they have no underlying real-world application.
limited supply, transportability, divisibility, ease of custody, low cost of ownershipNo, people actually do make that argument all the time. You're making it right now, in fact, because that's essentially what you're saying when you claim that Bitcoin is the greatest money ever invented. Why? Because the 21 million limit is literally the only thing differentiating Bitcoin from every other shitcoin on the market. The fact that it is strictly limited in supply is the only reason you can claim it has any value in the first place, which is in turn the only thing that makes it function as a perfect form of money (in your view).
What is money? Money is not paper, gold, or anything in particular. It is a ledger that keeps track of who has provided value to society. It allows strangers to demand each other's time, in a cooperative and mutually beneficial way. Fiat is a corrupted form of money, but it still is a ledger that mostly keeps track of that (bankers and government parasites not withstanding). 95% of fiat money isn't in the form of physical notes or coins - it is simply a highly centralized electronic ledger, subject to the corruption that centralization leads to.
Bitcoin is simply a ledger - the absolute genius feature of which is triple-entry accounting: double entry accounting with timestamps (which solves the double spend problem of a decentralized ledger).
