"Frankly, if there were a 'global currency' it would be de-facto something like a massive, well managed ETF fund whereby 'credits' would map to a portion of said assets. It could be anonymous, and maybe transactions could be decentralized - but - there's no getting around mapping the value of the currency or asset to some part of the system, they cannot be independent. And frankly it would need to be 'so huge' that it would imply a kind of Global Central Bank of some kind, which we would never agree upon." If everyone agrees on putting their wealth into Bitcoin, and then invests them into others, wouldn't that be kind of what you are describing?
