Agreed. The logical answer here is to limit the things HOAs can and cannot do rather than ban them outright. But that doesn't make for a good headline.
Same problem you have with any kind of local government: time. Busybodies with too much time on their hands will dominate. People who actually have lives to lead don't have the time to compete.
If the house is covered by an HOA, it's typically not optional.
And in some areas it's very difficult to find housing not part of an HOA. I think somebody mentioned elsewhere in this thread that all new housing in Phoenix requires an HOA.
