You can most likely afford to buy a viable homestead in a rural area if you wanted to. Your problem isn't that you can't afford a house, it's that you can't afford a house in San Francisco.

I sincerely doubt that you can't find food better than your grandparents' by any objective measure. I suspect this is just nostalgia. I've lived and ate at rural family farms before, and while they often have better tomatoes than a typical supermarket and other tiny perks, if I had to pick between getting my food from the family farm and getting my food from a supermarket every day, I'd pick the supermarket without question. And I can always go to an upper-end market or a farmer's market if I really craved high-quality tomatoes.

I have never had any complaints about the quality of my clothes, including clothes bought at physical stores. I'm not sure why ordering clothes online is a downside.
