Seems like it would be better to have a pool (or other common amenities) via voluntary contributions, leaving out the rules forced on homeowners' properties. And a voluntarily financed pool makes a certain amount of sense. Why should someone who doesn't want to be involved be forced to contribute against their will? That's not easy to justify.
