I get what you're saying, but I'm not sure I completely agree.
DriveThrüberRPG delivers pizzas from almost every franchise, and sends it anywhere in the world. KrustStarter sends out new and exciting menu items every few months. And there are tons of folks on Calzone20 or FoundryPZA that would love to share a slice with you, no matter what you're serving up.
Pizza, in all it's varied and delicious forms, has never been more accessible IMO. Certainly not equal... Pizza of the Coast is the clear leader and industry standard. But pizza in general is definitely accessible.
