"Which facilities are you going to nationalise?" (Volgadon)...large ones, such as all public transport, such that, via regulations and modern IT, one could by a ticket from, say, any bus-stop in Cornwall to anyone in Northumberland.
The problems you mention with the UN will have to be overcome to make is stronger and more democratic; but it IS the best way forward, and it's good that it's been talked about here - the English media, e.g., give heaps more attention to the US than the UN, which is NOT a good thing, and I sometimes do my bit by making emailed complaints about it.
And not that long ago, English club-football, e.g., was regulated (although not quite as much as I'd like) and was, indeed, mostly-locals in meaningful competition, rather than the greedy meaningless foreign-farce it is now.
Finally, you accuse me of not doing any research, but all I've just said is on my site, which I think you claimed to have read..?
