Answer 1

Anything can be a currency, even candy wrappers, if they are trusted by the population, if they have high liquidity. Can you convince the whole world that your candy wrappers have value? Not? It's clear.

Answer 2

All this is not here.
And security is just not required, and existing fiat currencies do not have it either.

Answer 3

No, because there is no blockchain and, accordingly, there are no connections in it. And what you described is ordinary tokens ala vouchers or gift certificates.
