Sometimes things cost more than people are willing to pay for them.

Public transit is an example. The postal service in some countries, lab-grown hamburgers, and most mobile apps are good examples.

Food delivery will be sustainable and profitable soon, when robots are delivering the food. Uber might actually be making money at it, for all I know.

Public transit is in massive use in many cities around the world where people are happy to pay for it. And it has huge economic benefits beyond the immediate costs of operating it.

I know, but that has nothing to do with my point.

My point is that it's a money-losing public service, not a profitable business in the vast majority of (or all?) cases.
