I agree with most of your comments. However, I wouldn't think of this as a capitalist-communist spectrum. In fact, I wouldn't think of either of them as long term solutions in this future. What both systems have in common is that they are built around scarcity. For capitalism, it is a method of price discovery. For communism, it is rationing by the state ("From each according to his ability..."). When there is no more scarcity, then there is no more need for either price discovery or for rationing.* Therefore, will need to create a new economic model that is not built on scarcity. *Footnote - there are some things that will always be scare, such as location. Having a view of a calm beach, or of boundless nature, or a city skyline will always have a scarcity issue. It will be interesting to see how that scarcity is dealt with in this future.
