I think this idea is interchangeable, even if electricity becomes cheaper, the price will be raised for something else
... And not the fact that this will somehow improve the situation
That's the point. Look at it the way it is.
If you have 5 sources for electricity, which one are you going to choose? The cheapest, of course... and cheap regarding quality as well as money.
So, which are your choices? Your ability to build and maintain your own electricity is one of them. When the others become too expensive, you will turn to your own, and make it yourself, right? Or, you will simply find a way to live without electricity.
As long a one of the 5 can box you into thinking that
"I am the source," he owns you. If you like being owned, great. But if you don't like being owned, start to think outside the big-picture-box that
#5 wants to keep you in.
