Since the government is so opposed to readers thinkers walkers and slow drivers why does it allow the procession of men along the railroad tracks to exist

In my opinion, there are two possible reasons.

First, the government probably does not think these guys are any kind of a threat to them. I mean, so what if there are some people out walking around when no one knows they're there? It's like the thing about the tree falling in the forest with no one around.
