For some of us who never got into the cooking habit, and can't do anything on a regular schedule (like food shopping), and can't plan in advance in general, and don't even have running water at work (old building), it's incredibly HARD advice to follow.

I live one block from a giant supermarket; I moved here FOR that supermarket. They have pretty good produce; if I walk 5 minutes there's a local food co-op and 10 minutes gives me Whole Foods.

But you know what's easier than going to the supermarket, picking out produce, planning or googling a meal, and [feeling like] + [remembering to actually] cook that meal before the produce goes bad?

Buying ten boxes of Amy's, congratulating myself on the fact that there are actual identifiable pieces of broccoli instead of green flecks, calling it "healthy", grabbing some ice cream and cookies to reward myself for that, and being all set for ten days, plus a buffer of whatever I actually had in the back of the freezer before.
