If it did, then following the reasoning of statistical mechanics it would mean that energy and quantum states evolve towards the largest macrostate, or equivalently larger entropy. This would be a dissipation of energy that would tend to mean these halos of DM would decrease in volume. This dissipation is one reason that galaxies when they collide end up gluing together in a single galaxy. This would then suggest if there are gauge field interactions between DM the coupling constants are very small and interactions extremely weak.
