Your argument would hold water if your "what ifs" were possible. But it has been opined on here many times that the restrictions you are suggesting are in violation of the POS and are near impossible for DVD to implement. Posing it as a question rather than a statement doesn't make it any less incorrect. Your fears about restrictions are in line with "what if aliens come down from outer space and blow up Disney World?" I guess it would ruin the value of my resale contract, but the chances of it happening are so infinitesimally small that it's not a valid argument.
