I have to comment on HOAs. I was once president of one for several years. It is one of the most unthankful positions to have.
If you would never live in a neighborhood with one then you would not mind if 1. Someone bought a bus and parked it in front of their house or in their driveway. 2. If a neighbor painted their whole house black or purple. 3. if a gas station near your entrance was serving alcohol to minors and letting people loiter on the property and drink, harrass customers, when the city did nothing. (We took their alcohol license.) 4. if a neighbor builds a carport in front of their house. 5. If a neighbor decides to build another house in their large yard or a condo to rent.
It goes on and on with crazy things homeowners will try to do.
I agree some can be overly powerful or lusting for control. Yet, most rules are to preserve the integrity of those living there so close together. It can get out of control, though, such as telling people to take down their American flags and getting picky about where trees are.
There have been crazy drone operators that really have gone into neighbors' yards, looked down over pools, even looked into windows. Society makes rules to try to keep us cordial with each other as much as possible. But the power to make rules gets out of control, too.
