You know, like they already do with this whole "fiat money" thing.
Nail on the head!
The only difference between "tokens" and "currency" is an army and taxes!
Countries don't all use their own currencies (and I don't just mean the Euro zone, this also happens with USD and used to happen with GBP), but they do all have their own taxes. Some countries don't have any armed forces unless you count the police. And the force of law is enough of a threat to get people to hand over crypto keys when they're physically in the relevant jurisdictions and the law enforcement makes that demand.
Sure. I think this missed the point.
I didn't say/intend "a country / army needs to be backed by a unique currency"
I said, "For a token to be a currency, it needs to be backed by [at least one] army and [at least one country's] taxes".
e.g. The Euro happens to be backed by multi armies and at least Germany's taxes.
> Some countries don't have any armed forces unless you count the police.
Again, it isn't "their army" but it is "an army". e.g. Liechtenstein is backed by "Austria and Switzerland under an informal agreement among the three countries." https://en.wikipedia.org/wiki/List_of_countries_without_arme...
Anyways, if we disagree that is ok too. All of this is quite fuzzy really.
