I'd be lying if I said it didn't bug me sometimes, but generally doing the right thing is it's own reward. It's a good thing, too-- the idea that people do well by doing good is pretty much a con-job.
Of everything you said, the things I agree with most are your comments on laws upon laws, and the need to selectively enforce them to a degree that it's all arbitrary, and left to the discretion of various public servants. This is the very definition of a police state.
PS: Dad was a plumber-- we do commercial HVAC service and specialize in supermarket cold storage (a niche corner of our small market without a lot of competition), but I've plumbed no small number of houses in my lifetime-- 1.6 gal toilets have gotten WORLDS better in the last 10 years.
