Quite right, and even apartment dwellers can easily have a few tomato plants. One thing that's critical is not to use hybrid (F1) seeds, they don't breed true / aren't reproducible, so you need to buy seeds every year. This means the plants will never adapt to your particular soil and climate. Unfortunately these are the most common seeds found on the market.
