I live in an urban area and everyone hates this one guy who just moved into the area. He never picks up the poop, neighbors are all pissed writing his landlord and everything.

There's only one tiny patch of grass on the edge of the parking lot and it's completely covered by his dogs poop. The poop doesn't go anywhere and just piles up and now the other people with dogs have no grass to use.

I think you're ascribing a moralistic principle to a comic that is intended more for shock value than anything else.

There is no lesson to be had here, and searching for one will only lead to madness.

I assume that's going too deep into artist motivation but you never know, they do make comics and those people can't be trusted.

The implication was that the absurd comic is meant to evoke arguing in the comments

There's at least one in my neighborhood, I think more, that have left piles in my yard. I need to set up a camera so I can rehydrate and aggressively return to the sender's front door.
