I would make the argument that people would have to weigh the cost of being accessible to the last 2% vs the cost of losing the last 2%.

Anyone who delivers mail to rural farmers 100 years ago would lose money. There are 3 options. 1. If farmers want mail, they can pay the extra costs. 2. Force, by law, mail carriers to deliver at a loss to farmers. 3. Rural Free Delivery, the government taxes everyone and pays for the free delivery to farmers.

Although almost all farmers in the United States and a majority of users on Hacker News would disagree with me, the answer is the government should continue to deliver free mail to rural farmers. The collective benefit outweighs the cost.
