Real-life situation(my own family): 1 adult, 2 seniors. In an apartment on a steep hill in the city. No car since 2008 - a rental is done maybe once or twice per year. There are definitely drawbacks, however, most of the large items, and the bulk of the groceries, can be done with an online order today. Smaller items can be picked up while out. (No regular jobs here - all independent business, contracting, etc.) It would be harder if this were a two adults-two children situation and the parents both worked 9-5 jobs. The kids would be more dependent, and it would be tough for everyone to hit the work/school schedule exactly. However, it wouldn't be impossible.
