HOA's are getting slammed alot here, but there is a valid reason for -most- of them, and that's to document in a legal way how to deal with common property and common problems.
I use to live in a very tighly packed town home community in the Washington DC area. Their streets all were owned by the community, so I would imagine that once every 20 or 30 years the community would have had to pay to have them replaced. So some of the dues collected by the HOA went into the pot to pay for the future replacement of the streets. You wouldn't believe (when I sat on the HOA board) some of the guys that would come in and make demands of the HOA. I remember one that wanted to have the HOA fees reduced to NOT cover future road repairs. Let some future owner get stuck with that bill (future enormous) as he would have sold his house and moved on.
Another owner wanted the local Army airstrip to stop flying planes over his house (the airstrip was there for 60 years before the community was built), as it bothered him. Of course when he bought his house the airstrip was there and the planes were there, but now that he was past that stage he wanted the local army airstrip to change their flight patterns.
Snow removal was contracted by the HOA. Towing was contracted by the HOA.
Towing was a great service, especially in my culdesack. We had no guest parking and only 2 spaces per house, which were numbered and assigned. Sure enough, time after time, I'd come home to find that my parking space was occupied by some neighboors guest, and the neighboor really didn't care that I couldn't park in my assigned parking space. I'd park down below the culdesack where there was parking for guests and others, and trudge up the hill and start to knock on doors in our 24 hourse culdesack to get my space back. It was amazing to me peoples response.
Me "sorry to bother you, but I'm trying to find the owner of a blue honda civic that's parked in my space xxyy right over there (pointing)".
Owner "Oh, that's my guest."
Me "I've been knocking on doors for 30 minutes trying to find out who owns that car. Can you have them move it."
Owner "Phil, someone is here and they want you to move you're car"
Phil "Tell them I'm busy, I'll move it in 30 minutes when I'm ready to leave"
Me "Tell Phil that if he wants to wait to move his car, he can find it in the towing lot"
Phile comes to the door "You rotten SOB, making me move my car. Who do you think you are!"
Me "I'm the guy that's going to have you car towed as you're in my space."
Owner "you're a terrible person."

Phil (grabbing his keys) "Rotten SOB"

Me "I just want my space back."
About the 5th time that happened, I finally just gave up and would not knock on doors to find the person and get insulted. I'd just have the car towed. Then about 2 hours after I was settled in, there would be a knock on my door.
Owner "Do you know what happened to my guests car? He was parked in space xxyy right over there (pointing)."
Me "Yah, they were in my space, so I had them towed"
Owner "WHAT!"
Me "bye"
After a few months of that, I found that my space was no longer filled with other peoples guests.
And just to be clear about it, there were signs every 20 feet all through the neighboorhood saying "Assigned parking, Towing enforced".
I moved about 15 years ago.
We have no HOA on our private lane, and there's plenty of parking in our county setting. Since there are 5 property owners on a private lane, then the county puts a document into each mortgage that states that the owner is required to maintain the private road. 4 out of 5 of us property owners fee up every 2 years to buy milling, but for 1 HO they don't want to pay. I've badgered them in the past to get it (late). If they just decide not to pay this upcoming year, then I'll have to pay their part, and then sue them in small claims.
So my take on it is, HOA's are a necessary evil for densly packed neighboorhoods, and their rules and requirements should be less and less as the density of housing goes down. But as long as you have a shared resourced that everyone needs to maintain, you can't get away from them in one form or another.
God is great. Beer is good. And people really are (some of them) crazy.
