It's pretty much the same with gold that people can't print out of thin air, and despite it is being praised as money (ignoring how inconvenient it is), the fact that it is something people hoard makes it by definition bad money.
I don't think we'll ever get to experience a Bitcoin or gold standard anymore. Money has to have the inflationary characteristic so that it isn't scarce enough to endlessly hoard, which is something fiat does right.
I rather keep hoarding Bitcoin than spending it and there isn't much that will be able to change my mind. Even if fiat as we know it implodes, the government will issue a new form of money. Bitcoin and gold will still be ignored in that case.
