I wish pointing allowed you to place a Nav point. Nav points are so critical in team play in rallying or sharing finds. We certainly need no and yes emotes. I'm not sure if an entire Tower Prox chat is needed. I can see the issues on why Bungie chose the format they did. I would say pick a few lounges and Prox chat them like the one at the bottom of the hangar. Or place a amphitheater meant for Prox chat in the Tower where players can mingle and talk with out contaminating the entire Tower experience.
