I agree 100%. In fact, one time, wife and I got a beer at Rose & Crown and then left Epcot via IG. We were not done with beer, so we put it in stroller and snuck it out (I know - this was evil and wrong). As soon as we got out of park, we saw some characters over in the French courtyard, so we wanted to go back in. At that point, security would not let us back into the park until we finished the beer that we had just snuck out of the park. I know I created this problem for myself by breaking the rules, but it would be nice if they would let you take beer in or out to avoid this.
