A lot of interesting questions here, and no quick answers. In my opinion it would be good to have a society where there are some centralized functions like the justice system and access to medical care for all for example. And I am willing to pay taxes to have that. But would be happy to see that taxation was based on resorce consumption rather than work.
And as a side note, lab grown meat will probably be a huge transformer of the world. It will lead to big changes through less energy consumption, freeing a lot of ground to grow crops for feeding the whole human population and a shift in mind set about about how we treat animals. And, if if my goal in life was to get a Nobel prize, this is the field I was going into..
