Much as I hate to take the suggestion too seriously as, unless you happen to have a secret contract with the UN, this is purely for 'silly season' discussion, but you could argue that this is exactly what happened throughout history and the creation of the states we have today.

Just one example; Scotland

Scotland joined with England to "share" systems, but mainly to share access to trade and the colonies (having bankrupted ourselves trying to create our own one ... in Panama. Doh!). However, I don't think this was entirely a "free" vote as there was a great deal of inducement involved.

It is also the price you pay for getting any support from the World Bank or any other international body run by the 'First World' countries. 'Free advice' for poor countries - "... but if you don't run your country as we tell you, then we take the money away"

Could you please name a single country that you would willingly franchise yourself to? Alternatively, name one that is so well run that others could or should emulate it? I think you'll struggle.

I certainly would not wish to push the UK system onto any other country. We tried that in the past and that is why we are so loved all over the world!
