All this discussion misses the basic point - the magic system in D&D was never designed to be implemented on a societal level. It was designed, right from the outset, to let players take their characters into dungeons and kill stuff.
Think about it for a second. Why is Continual Light/Flame (depending on edition) a second level spell? It always has been, but why? Well, by the time the group is 3rd level, they can start staying in the dungeon longer - they have the resources for extended forays. However, if you have to hump 50 gallon drums of lamp oil into the dungeon so that you can see where you're going, that gets to be a PITA.
So, enter Continual Light/Flame. Now you have an endless light source so you don't have to go back to town to stock up on lamp oil or torches and you can keep adventuring.
The same thing goes for virtually every utility spell in the game. That's WHY those utility spells are so low level. They are there to help you clear out the dungeon. What effect low level long duration magic would have on the society as a whole was never a design consideration.
If you want a fantasy world where the D&D magic system actually fits into the setting, rather than a tool for adventurers to go have adventures, then you need to redesign the magic system to fit that goal.
