It's incoherent to use the example of low service density as a justification to criticize a grocer for taking higher profits. You can't pursue both sides of a tradeoff simultaneously. The more money there is to be made in the grocery sector, the more grocers there will be to compete for it, located in the places where the money flows. Likewise the leaner they have to operate, the more they'll shut down in marginal territory that can't support their business, and the more areas will go without convenient access. If selling groceries in low-access areas for low profits is indicated by the necessity of food, then nobody is stopping you from doing it; but as the grandparent comment hinted, if you find your niche in high-margin software instead then you're following the money, just like grocers do.
