With infinite possibilities, seemingly bothersome restrictions may not make any difference.. it may even demoralize to loosen restrictions or “burn family pictures to keep the house warm” when one could deem them absolutely inflammable and magically manage to find other fuel.
In episode 7, season 12 of South Park “Super Fun Time”, we see Butters adamantly refusing to let go of Cartman’s hand (it violates his very nature to break rules!) and the cast of the historic reenactment village adamantly refusing to break character. Despite refusing to budge on these seemingly petty issues, they triumphed anyway. Is the notion that restrictions could make the otherwise possible impossible may be very unlikely.
Here’s the real world scenario – torture
Forgetting for a second the heinousness of using torture, is adding it as an alternative likely to make impossible things possible? Will some disaster occur that could have been averted if only we allowed torture? Unlikely, though the uncreative mind would disagree. Notice that Cartman and Butters don’t even mention the possibility of letting go to get on the truck but go with the more elaborate swinging around. Cartman plays along with Butters’ more, just as Stan reluctantly does with that of the reenactors.
Imagine the hollow victory that would have been won if the cast broke their years-long (hey, they had a reputation that even the 911 operator knew of!) vow of in-character in this circumstance. It would then be excusable in any number of circumstances to break character. How sad that would be.
