Duplicate the means of production. If we really end up in a world where robots make the products and robots make the robots, then the means of production are information products that can be copied like software. (And there will be open source robots too, but copying without permission is the fallback position if commercial robots are too patent-encumbered to reimplement by legal means.)

I wouldn't steal a car... but I wouldn't feel a bit bad about having a machine build an identical copy of a friend's car for me.
