I'm not saying it's unfair. I'm saying you can enter into a business where you have a competitive advantage based on location and run said business profitably, and that's not a mistake.

If it didn't work, we would have no gas stations. I don't know about you, but I'm not so loyal to a particular gas station that I would drive farther to reach it if there were others more convenient to me that offered the same service for the same price. That doesn't mean it's a bad business. It means there is competition with fairly exact substitutes, and location is a big part of success.
