That's only a benefit if you're interested in variety. For a lot of people, their idiosyncratic tastes are things they _don't_ like.

My thoughts exactly. Great, there's food at home, ready to eat, 6 days a week. Can I eat it though?

I'm sure in an ideal world you could get past that problem by talking and having everybody else compile a mental list of what meals aren't going to be on the menu, but the more realistic outcome for someone like me is the food only being edible for me 1 or maybe 2 days a week, not to mention that I'll probably come of as an knobhead for not liking their food and making my own, and them probably not liking my food when it's my turn to prepare. It's a manageable situation for a couple of days or say a week, especially since everybody else is probably more willing to accommodate if they only have to do it for a short while, but I would never want to deal with that even semi-permanently.
