That sounds great but how do you deal with the fact that robots require mass-produced electronics and the infrastructure for those is currently in the hands of, well, let's say not anarcho-communists?

How about the environmental costs of all that automation?

Is there a realistic path for getting to what you propose from where we are now?

[Edit: realistic in the sense that e.g. the Alcubierre drive is possible but requires exotic matter, therefore "not realistic").
