I think that this is interesting question.

It has been already pointed out, that cooking/eating at home is not just a way to provide fuel for your body. There are many other reasons, like: - pure fun - social activity - adjusting the meal to your taste - not having to go outside (especially when the weather is bad or you're sick) - a way to save money (but you've proposed an alternative for this) - eating healthy (it's very hard to eat the right amount of good quality food outside)

On the other hand, I've recently heard about a new marketing campaign by IKEA in Poland, where they opened a "social kitchen", where you could book some time and hang out together with your friends.
