I don't even know what you're talking about with this 'Freedom to leave a marriage' part. It seems like a smorgasbord of ideas smashed together rather incoherently, my apologies but it's after lunch and maybe my brain isn't all functioning 100%.
Ok I also don't understand what you're talking about in 'Fewer mental health isues' either. It seems like you're trying really hard to imagine a fantasy reality where non-heterosexual people can live by themselves - but with a partner if they want - but they can leave - but they should be able to leave and be by themselves and be just fine - all with regard to COOKING specifically. Am I getting in the ball park there? I don't really know what you're getting at. When you deviate from 'normal' culture, life is going to be harder for you. That's how our world works. The people that have and are trying to change that... just watch for if things are getting better in their wake, or worse in their wake.
I suspect economic stability comes more from personal responsibility than 'personal flexibility'. One must make great sacrifices, in general, to develop the character to be able to progress in most areas. What I typically see from the crowd wanting more freedoms is the freedom to be more hedonistic, where I see the people more grateful to exist and actually progressing growing their discipline and losing their selfishness.

>>> "It seems likely to me we need to rethink and rework our food culture so everyone can eat adequately"
How could the second work without fixing the first?
