I respect your technical expertise, and have no doubt that your theories would function, within a civilised and stable environment.
But I think you ignore human nature and the genetic forces that drive us to survive at all costs, and the ineviable destabilisation that will cause when survival is seen to be at risk.
Human nature installed the current crackpot in the USA. He is not the cause of problems there, just the symptom. The same far right elements are rising in Europe again, as we have seen in the past.
Each promises the impossible, and the unthinking masses believe it, certain that the problem is political, not environmental, and that ‘others’ are to blame for economic woes.
With this in mind, the necessary ‘world order’ to bring about your interplay of technologies would be almost impossible. Starving millions are on the move now, their single goal is survival. They cannot wait for the reorganisation of the global food production system, they want food tomorrow.
Once fed, they will obey instincts and reproduce — just like any other species. Not being callous here — just realistic.
As to ‘low oil prices’, the money paid per calories of energy relates to the energy we expend to get hold of it. (I’m not explaining that very well)
Right now, we expend 10cal of energy to put 1 cal of energy on our plates. We have got used to that, it gives us overflowing supermarkets year-round.
I doubt if your ‘system’ would allow that ratio to continue, despite the fact that food surpluses on the current scale have only been with us for about 60 years.
But we demand that that goes on. When (not if) that ceases, there will be civil chaos.
We have spent the last 50k generations locked in a battle for survival at various levels.
We have 1 –2 at most — generations left to change our ways. Past history leaves me somewhat pessimistic in that respect.
I think the creation of the infrastructe to put all that in motion would also be beyond our energy-means, let alone political will.
