> From their perspective, they get to found little vassal townships where they can say “it’s your problem” to little people problems like “there’s too many potholes in the road” and “that sewer lift station is making weird smells.”

Roads and sewer are two things I've never seen an HOA have jurisdiction over; in every HOA community I've lived in, the municipality still owned the roads and the water and sewer infrastructure. The HOA was only responsible for things like mowing the grass in common areas and maintaining play equipment there.
