Free food to me is worth more than $10 per meal. It's the time that kills you. If you work out your rough hourly salary and calculate how much money you waste making food then it's worth thousands of dollars a month.
Another way to calculate it would be to try and figure out what you would pay for another 40 minutes in a day, but that starts getting very subjective very quickly.
I cook to relax, to get away from the computer.
Now, if making your own food makes you happy and you want to do it, do that. Of course. But having the option not to do that. How is that bad?
;; Though if it is thousands a month to you then you are either much better paid than I have ever been or are going all out on your meals. :)
Add tofu, soy sauce, and green onion (45 seconds of effort)
Let it cook/cool down for 10 mins (other things can be done in parallel)
