“ There is more than enough for everyone.” The basic untruth at the heart of your manifesto. The planet is finite. Carbon based fossil fuels will run out one day even if they outlast the looming disaster caused by their consumption. And, who are you including in “everyone”? The statement may be true about Britain — I doubt it’s true of the whole world. And your objective, as made plain in the essay, is a planet wide adoption of your ideas.
And all that automation that your vision depends upon takes vast amounts of resource to construct and fuel the machines. Any system that fails to recognise the importance and value of human labour is doomed to failure. That is the only resource that will never run out.
