That sort of cynicism is needless. Considering that this thread is about private prisons, a very serious issue, bringing up a literal straw man is disingenuous and completely unnecessary.
It's not a strawman argument if that's really what they are spending time on that should be spent addressing far more important issues like homelessness. They shouldn't spend 1 second talking about an issue so meaningless on the list of issues they need to tackle. If you can't see that they are grabbing at low hanging fruit so that they can say they accomplished something then I think you might be a bit naive. A ban is literally the easiest cop-out for legislatures to do. No deep thinking required to blanket ban everything you don't like or perceive as problematic.
