For your supermarket example, instead of going there you could go to a local farmer's market for those vegetables. It might cost more, but most expect higher quality there than at the supermarket. So there is another "market" option, you shouldn't just expect all your "market" options to be placed in convenient aisles at the grocery store.
If you live in the city and have to drive over an hour to get to a farmer's market, well that was also a choice you made. Perhaps you didn't make that choice because you wanted to be away from locally grown produce, but the supermarket being your only option is a consequence of that choice.
I'm not trying to be a jerk, just trying to point out that much of the choices we make will reduce the other choices we have and we should be conscious of the ones that drive us to become mindless consumers and remove other options from us in the market.
