Litecoin also has four one-megabyte blocks per ten minutes, doesn't it?

So already offers four times as much transaction-space as bitcoin?

I am also not convinced that "one world currency" constitutes "decentralisation" of the world's financial systems.

Possibly it is better to be able to move elsewhere each time the powers that be grab control of some huge majority of the money in any particular system, maybe even go for agility where they are constantly on a treadmill trying to grab a majority of more and more and more new systems until maybe in some distant era they will realise no matter how much they want to control everyone, some people will (one maybe hopes?) find some way to retain some freedom despite them.
