You've missed the point completely. You don't prohibit people from serving, you prohibit people from doing business with the corporation while they are serving. An Agent representing shareholders is, for all intents and purposes doing business with the building thru the shareholders, and profits by the approval of their work efforts. That can be viewed as collusion, self-dealing, using the friendship and working relationships with other Board members for unfair advantage in the review process, etc. There is no arm's distance relationship, no barrier, no wall. Recusal is nonsense really, as it obviates the existence of the personal relationships, and won't withstand the inherent skepticism of any affected party or the court. They can serve on a committee maybe, but on the Board while actively doing business in the Building, and inherently giving the impression, by virtue of their being a Board member that a shareholder selling will do better by using them, is an unfair, unspoken advantage. This isn't brain surgery. Appearances are a form of reality, and it automatically colors the other Board members in the process whether you like to admit it or not. Perception is always it's own special reality. There's a whole world of apt. buildings out there to make a living from, you don't need to be on a Board and do business in the same building. You can advise and consult without that. Your advice might be invaluable, but being on the Board undermines the legitimacy of the service rendered. It leaves the Board and the Agent open to a level of questioning that is both unnecessary and destructive to the level of trust the work requires from everyone. No matter how small the Coop, there will always be a few who will question it. IT's the sad side of human nature, but too often isn't off the mark either. There are enough articles on self-dealing each year in Habitat to prove that otherwise. Regardless of the pride you have in your professionalism, integrity and character, it doesn't mean that someone, wrongly, will still question it anyway, just because of perception issues. Unless there aren't enough decent, qualified people to even fill the seats, one shouldn't undermine oneself that way. It diminishes the value of your contribution, and that would be a shame and a loss to the building.
