Earlier quoted context omitted.
I’m saying sleeping on a bench that is meant for transit users to wait for a train is, indeed, anti-social. This is fairly trivial to demonstrate using a categorical imperative. If everyone used the transit system to sleep in, then that transit system would likely cease to exist, and the benches would not be maintained. We very much ought to have places for people to sleep. That those resources are rarely provided to…
Homeless people have no moral obligation to stay away from benches due to "solvency of transportation systems", if society doesn't care about them in return.
If we live in a would where we accept that we allow some folks to disrupt complicated social programs, then those aspects of the social programs will disappear or the programs themselves will disappear.
This is exactly what the essay describes as happening. When someone on a bench disrupts the service and we will not remove the person creating the disruption, then we will end up removing the bench.
We can clutch our pearls all we like here, but people will stop using a social service they are uncomfortable using. And when they don't want to use it, they will stop funding it. As long as we live in a democracy, this will be in issue.
