You can think of it as an investment which will take 5-10 years to mature with a secondary benefit of backup power if the grid goes down. Not everyone can afford it, but that's the nature of investment.
Also in Chris' scenario, he's using America as the model. Electricity costs there are just over half those in Australia.
