Sorry, you lost me.
Close co-operations are planned for in every corner of the globe, to make goods and services affordable.
I would expect Orania, The Cape of GH, Lexiland etc. to be well-entrenched in close cooperation, if not by the time of their independence, then soon after.
Also, does your answer explain why you could not construct a smaller version of a coal-powered energy plant?
In terms of distribution across SA, if SAns stand to benefit, their government will respond to that expectation and facilitate mutually beneficial trade with these independents.
Do you think the ANC, post indpendence, would be able to sustain its criminal behavior as though no CI etc. had happened?
Think about it, it would lose its trump card i.e. the race card.
