The problem with that argument is that the greater efficiency will just drive for harder difficulty, and thus require more hashing per payout. Ultimately the power consumption will always regress to the total payout divided by the average electricity price no matter the efficiency of the miners. Some different non-mined altcoins don't have as much of this issue and I wish they were more popular/more people tried to figure out how to make them work better since they still seem to be in their infancy due to the other attacks they are vulnerable to.
