Earlier quoted context omitted.
Making it illegal to be homeless means making it illegal to be homeless. Not just in encampments. They said homeless shelters have a lot of drug activity. You implied encampments do too. What was your point if it wasn't about encampments?
Their point was about drug activity being a problem in shelters relative to encampments. Your comments about making homelessness illegal seem like a non-sequitur.
xnyan explained problems with shelters relative to unspecified alternatives. They didn't mention encampments either. The comment they replied to didn't mention encampments. And you pointed out some of their points don't make sense if they were just comparing to encampments. The strongest plausible interpretation of what they said is they weren't just comparing to encampments.
