I do generally think (and agree with rightwingers) that central planning suffers from new categories appearance, if there is no vision (say, cellular phones), there is very small group of people which will deny you funding/allocation/workforce, while capital allows say 50 banks to shop around with business plan.

This problem is solved in a communist world if we eliminate borders by allowing people to make their case to any administration they want instead of just the administration in their home country. There can be options because there will be hundreds of different administrations optimising for the specific local conditions they have.
