Isn't a better analogy that we have invented some new type of window glass that is the future for all homes, but there isn't overwhelming demand in the free market for it yet (due to price incentives); therefore, we should break some legacy old-glass windows every month (and subsidize their replacement with new-glass) to support and accelerate (inevitable) adoption?
