Well, this whole thread is a glob of implausible proposals justified by implausible assumptions. "We'll eat no more meat or bananas!" "Because we won't burn any more oil!" "Because oil will be illegal!" "Because sustainability!"
This is all just silly. Credit to 'workthrowaway27 for responding in reasoned fashion, but that hasn't dissuaded any of the silly folk in their silliness. They suggest catastrophic changes to the lives of everyone on earth, and the reasons they offer are transparently based on personal psychological idiosyncrasies rather than on a practical understanding of reality. All of this tyrannical bullshit won't happen, not only because it shouldn't happen, but also because it can't possibly happen. One does admit it to be a lovely dream, because one understands that lots of people dream of denying the agency of other humans. This is an impulse to indulge in daydreams, not in the political sphere.
