But there will always be scarcity of something: materials, energy, land. Things will always have a price, because they at least require energy and space for production. It will be unbelievably cheap, but never absolute zero. And then someone will own the land (along with what's underneath) and the machines themselves, unless of course we dump private property altogether. I don't see how this is substantially different from what we have now. It's just the machines will get better, living standards will be higher, there will be more bullshit jobs, and more time for creativity. So essentially the discussion comes down to whether there will be private property rights in the future. As someone who grew up in the USSR, where nominally there was no private property per se, I can only say the humanity will need a very, very good reason to abandon it for good. It's almost like saying prohibit sex in all of its forms and purposes, i.e. going against the nature.
