If you're at a public school, the school can no more stop you from joining an off campus fraternity than they can stop you from attending a certain church, joining the Lion's Club, etc. As far as the purpose of the organization though -- I'd have to wonder. I guess you could exist apart from the school, but really, what would be the point? I really think that my organization is so intertwined with the workings of the school that the two are difficult to separate.
