So, just curious but what is the point of the discussion? Is it just a philosophical discussion or are you hoping to implement it in game?
I am far more likely to be GMing than playing, so like to explore things that can be done in game for plot potential; frex a radio station that helps maintain spells and is so rewarded by spellcasters to the west would be a potential recurring location. I also like playing with what can or cannot be done to develop a world. Half a century after D&D was first developed, most game systems are still stuck in the same state they were first created in; that struck me most intently when Wonder Woman came out, as I started my first Boot Hill campaign in the 1980s - if I'd kept it running, and advanced year by year, I would have been using WWI for plot when that movie came out.
