Out of interest how are they going to stop you from not allowing weeds/flowers to grow?
HOA's are the worst way of making sure people don't treat their property like shit. Better ways include: fostering a sense of community. Communicating with your neighbors. And finally, minding your own damned business.
Look, I loathe HOA's as much as the next person but this doesn't pass the Chesterton's Fence test. If your alternative doesn't handle the case of an uncooperative antagonistic neighbor then it won't at all be persuasive to someone is pro-HOA. "Just stop caring about the problem that HOA's were established to solve" only sounds good to people who arlready agree with you.
If the homeowner having rights is a problem, I suppose an HOA solves for that, otherwise I don't understand why the pro-HOA view need to be privileged at all.
HOAs have a ton of "power" and it's why subreddits like https://www.reddit.com/r/fuckHOA/ exist.
