The thing I don't quite understand is that okay, let's assume that electricity CAN be transmitted to any point of the Earth with minimal loss. So now where does that electricity come from?
People tend to rip on Edison for - allegedly - not supporting Tesla's wireless transmission project, because there was no way to charge for the electricity. They make Edison look like some evil top-hat, cigar-smoking capitalist who sides with greed as opposed to science...
But come on... if I have a wireless transmission system, then I have absolutely no way to control access to the power grid, which means anyone can abuse the system and black out their neighborhood in order to try and power a home-built pulse laser or something.
It's a transmission system, not a production system. It would still need power plants, and provide a finite amount of power.
So I either go around with armed troops, looking for "pirate" access points and arresting people for having them, or I have the populace pay a flat tax for electricity, which would, due to the uncontrolled nature of the system, likely be a lot higher than the power bill of an average family.
