You don't need to tell me those things, I agree. However, these days there is no chance that Disney will have a store sitting there selling nothing. Part of the show or not.
However, I would say that in the past it had managed to keep itself above water, now though, I don't think that is the case.
I'd argue that the shop isn't even a loss leader (and when WDW allowed them, it's entire product was considerably higher quality than what they shovel today) because all it takes (at those price points) is 2-3 guests a week to buy a few of the pricier items to pay for the location for a long time. And I have seen people do just that ... often they're from the Middle East or native Americans who just opened casinos (the Seminoles shop very well at WDW!) and even the occassional geek from the heartland.
Disney is trying to kill the shop. To what end (Starbucks, vinyl, plush, a meet and greet) I can't say, but something is up ... would be nice if the people who cover WDW (hey, Yee, talking to you!) in the fan community actually looked into it and didn't simply accept a stock answer.
