Weldon - I think people get that you should not rappel using paracord except as your final option - especially since 8 or 10 posters said as much above.
I can see the basis for your concern, but I don't think discussion of this is will encourage people to try rappelling with paracord for kicks. No more than discussing what ammunition to use against Bears will encourage people to try and go share some meals with grizzlies or discussing improvised shelters and water collection methods will encourage people to hike off into the desert without water or shelter.
