All of Comic Con is scalping. Do you need the new Yuuzhan Vong figure? I'll get it for you at Wal-Mart for $6.99 right now. But if you want to pick it up from me when you come to Comic Con, it will cost you $55.99 plus a service charge fee ;)
or to scalp to folks in line? It'd just create the same exact problem there is now, except with the added cost and time used on taking tickets, and even more cheating.
Good point. However, I always see people standing anyway.
The fire marshal doesn't allow standing-room viewing, you must have a seat to be allowed into a panel room. Hell, that's the reason they have to use tickets for the HasbroToyShop booth now, the booth is so popular that it gets capped by the fire marshal. And that ticket system is a mess.
