It does not take more than getting free energy out.  Beyond that, no "logic" needed.  100% of the cost of everything is energy - the resources sit here freely but it takes energy to put them into useful configuration.  Add free energy and the cost of energy will be removed all down the line.

Eventually it will get to the point where collecting the penny for [whatever] is more energy than it's worth.  I estimate about a decade from the time the free energy flows.
