Depends. Most suburbs and towns have convenience stores at least where I have lived. USA might be different. Delivery is another option.
It's not forced - we choose to buy them ;)
Is it really a choice, when you have no practical alternative?
I have a choice, I can live in a walkable place, but it involves tradeoffs that I don't care to make - because I don't see car ownership (or driving) as a negative thing, unlike this echo chamber.
