I'm going to answer this question - how are you going to police this? More importantly why would Disney invest resources (staff time, money and/or computer resources) in policing this?
I regularly travel with non-running friends who humor me when I drag them to the Expo. To then tell them "oh, I'm going to go into this area, but you can't" would be a total deal-breaker. I like where they are going to with the Dopey merch (although honestly, just ordering enough of this merch to satisfy the reasonable demand would be better), but I think that this could be a slippery slope.
