Hide BuddyPress Member Directory

Hi, I don’t want the list of members available to visitors OR registered members of my site. Right now it’s all that’s included under Community. I guess I can’t use BuddyPress without the Community tab. Maybe I can stick something else in there… Or maybe I don’t even need BuddyPress. Maybe just WordPress and Membership. Can that even work? What would I lose that might mean that approach would not be worthwhile?
