The problem is that it will be affected. There is no friction to keep all the little bumps and jars from building up. And this isn't just about human bodies, every piece of equipment, inventory, and even the circulation of water and air will move that baby around. Sure when compared to the mass of the relatively stationary architecture of the station they seem small, but they're always moving and it will add up.

But, as I said, the great thing about Lagrange Four and Five is that an object with an orbit close that Luna's Trojan orbit will be pulled to that specific velocity/trajectory over time. I'm just not sure this balancing force will be sufficient.
