The utopia in star trek depends upon all basic needs, all necessities, and all luxuries to be supplied at no resource cost. Anything short of this star trek's utopia does not exist.
Star trek themselves addresses this in many many episodes. It was a key issue in the Voyager -> Kazon conflict.
>Ordinary volume manufacturing can cover that nicely,
This happened 150 years ago. It's what anti-capitalists are fighting against. The industrial revolution happened immediately before karl marx was born. This is what created the possibility for Marx to exist. Yet today for whatever reason the communists fight against this very thing. Boggles the mind.
If I were a communist, the path to communism is full robotics and automation.
>and more sustainable approaches can be used when we cease to program obsolescence.
Yes, a more modern problem of foreign manufacturing sending intentionally poorly designed goods to harm the wealth of our nations. We should be seeing planned obsolescence as a national security risk and set tariffs so high these planned obsolescence stuff goes away.
