Dunno... how on earth are you going to inspect cord connected appliances (like the range w/o strain relief) and minor construction stuff like putting up new drywall?
Call for a constrution permit for everything that exceeds hanging a picture using thumb tacks?
Regarding the range one possibility would be to outlaw any modifications by non-licensed electricians other than a) plugging and unplugging stuf and b) changing light bulbs. This is reality in many countries and also some states of the US (I think NYC for example is that strict) and doesn't keep anyone from doing hack jobs.
I think even in the most conscious country I know, Switzerland, this would only fail if somebody reported it.
