Where exactly is the strawman?

Parent made argument that zoning is the whole problem, is bad and entrenches home owners.

I provided two - albeit extreme - examples, why zoning is important.

Methinks that the consequences of the libertarian arguments of DAMN REGULATION! are quite often rather badly thought through. And that's what I wanted to point out.

Don't want to live near a tannery? Then you probably should be careful, when arguing for the abolishment of zoning and building regulations.
