Here's the reason, plain and simple: "It has been pointed out that US lawmakers are often very keen to stamp out any innovations which might loosen the grip of the big energy companies over the lives (and bank accounts) of the American public."

That's it, folks, that and the fact that it's harder for the government to control those people.

Why am I not surprised. A long time ago, they outlawed building concrete block houses. Only buildings a certain size and outer structures like garages. Having worked in masonry during my summer hiatus I pondered the costs of one and realized how much cheaper one could be constructed. One could add poured insulation. The builder could leave a lip on the base block so the owner, when more financially set, could add brick for appearance. But no, no cheap houses

Buy the land and tell them to fuck off..

I think it's a bit misleading . It's a local government ordinance thing. Not the federal government. This trend is irreversible.
