Agreed. My GF lives in a subdivision covered by one, and works from home a lot. She sent me a text one afternoon a few weeks ago that she had to go outside and help break up a fistfight between the neighbors on either side of her. Evidently Neighbor A took exception to Neighbor B's plans for a fence. Which were evidently approved by the HOA, but whatever.
The entitlement... worry about your property. I can understand if there's something that comprises a health or safety risk, but that's why we have building codes and doing zoning laws. And even those cover far more than that just about everywhere. Your claim (unsupported by fact) that your property value will be negatively impacted by someone's wholly legal and unremarkable use of thier own property.
