How is bitcoin like the gold standard? Bitcoin is backed by what? It's more like a purely speculative currency. It's artificially scarce and worth nothing apart from it's perceived value. At least with gold there are many industrial uses for it. You can't do anything with a bitcoin other than trade it.
You have to pay taxes and also settle debts in the official currency. That alone gives it more than mere 'perceived value'. Oh, needing it to buy oil also helps.
Precisely. Holding an official currency gives you the ability to stop the government from putting you in prison for nonpayment of taxes. This is a real tangible value that is a sort of baseline value store for official currencies that does not exist for other currencies.
Power doesn't come from the gun, but from public legitimacy. In the same manner that it would be considered legitimate for someone to defend themselves with a gun.
