Agreed on all. I'd like to add it also pains me that the power to produce about five times more light for the same electricity expenditure has been given without question or qualification to most of humankind, and yet almost no-one seems to ask themselves whether keeping spending the same energy and producing about five times as much light is what they should be doing...

Yes, the thought has occurred to me. This one seems particularly egregious, since it often results in going from a reasonable quantities of decent quality light to noxious quantities of noxious quality light.
