In general, assuming we've already given up our privacy and it is gone forever, Google+Government can read our thoughts, email, shopping patterns, knows our positions at all time, would it be possible to even create an optimized planned economy.

> would it be possible

Apparently computer controlled central planning is performed by linear programming, so if you fix the information problem of knowing exactly what products there are, and the inputs and outputs of all practical ways of making them, the complexity is O(n^3.5) where n is the number of distinct goods.

I don't know if the economy is creating goods faster or slower than society's capability to solve LP problems is increasing.
