That concept of "own" is what I think has to go away. The concept of "everyone loves what or who makes you feel good" is an interesting concept but is it true? Is love simply superficial bliss? Pleasure?
And by robotic economy are you referring to this article:

''own'' can't go away, cause in most cases we can't co-use things. The concept is focused on ''everyone'' - note that. It is not the thing but the one who delivers it. Usually is very addictive thing. And the one has power over the supply of the thing. Carrot coercion. Much more efficient than the Stick one. NO I do not reffer to this article or any article which names post-economy ''communism''. Communism is extreme form of decapitalism - i.e. based on dissipation and waste of capital: human, machine, nature. Post-economy is a process where scarcity, i.e. the necessity of choice for wider and wider fields of consumables disappears.
