The homeless population already exists: changing the metro to proof-of-payment or no-payment just concentrates them into the buses and subways.

44% of SF homeless have been in the city for less than 90 days[1]; the problem isn't that the city's welfare system is inadequate, it's that it's better than other nearby cities' systems.

Pragmatism can still be wrongheaded.
Some people see a system that attracts the poor and the sick as, if not a fait accompli, at least a damn good start. Now we could talk about the problems SF has with paying for everything, but that's the opposite of homelessness.
The Economist is advocating free public transportation ceteris paribus. They are not arguing that public transportation should be made free AND that the social welfare state be completely revolutionized. I (and others) are pointing out the problems that will arise if this change is made without making any other changes.
