If HOAs were of more benefit to all than reward to the entitled they could and would be organized by the actual owners of the property and not the previous owner.
In fairness, it would be hard to establish an HOA in a neighborhood that never had one. Bylaws and dues would only be enforceable on people who signed on to it. It's not like 50%+1 can vote to join an HOA and then enforce the rules on the whole neighborhood.
For new HOA's, I'm not sure what reward there is, or who the entitled are. Developers buy some land to develop. If you buy a lot you have to agree to the contract. At some point the HOA board will form, usually after so many lots are conveyed. Who is being rewarded other than Karens who orgasm over controlling other people?
You pay dues which pays for common area maintenance, street lights (if the local government doesn't pay for them). Snow removal. Sewage, if there's a common septic. Stuff like that. No one's getting rich unless they're abusing their power. I'd prefer not giving people power to abuse, especially when you're talking about establishing essentially a private government.
