You're expanding the scope to a much larger process and pattern of behavior that has to be undertaken and managed. Sure it's doable, and you can save a bunch of money that way. But as a one line throwaway comment it's still nonsense.
Also freezing things or letting them sit in the fridge for weeks tends to change the texture. A main point of a burrito shop is the fresh ingredients.

No, absolutely not. This sort of thing is seriously just the baseline of how we should be expecting people to act in society. Buying stuff for one meal at a time is ridiculously decadent behavior and should not be affordable
Well, you also don't have to freeze anything. When you cook almost every meal, you end up using most ingredients before they go bad. The ingredients for a burrito are pretty basic and can be used to make all sorts of things.
