I agree with that distinction. Also, making food for many people is much more rewarding than making food for just yourself. (When I do the latter, it's lots of work for 5-10 minutes of payoff, and I often find myself wishing I'd ordered instead.)

Many baked goods are easy to toss in a box and bring to the office or to friends' places. You're not going to bring a tureen of polenta to work and tell your colleagues to dig in for a midday snack.
