We find spuriously large repulsive many-body contributions to binding energies of rare gas systems for the first three rungs of Jacob's Ladder within Kohn-Sham density functional theory. While the description of van der Waals dimers is consistently improved by the pairwise London C-6/R-6 correction, inclusion of a corresponding three-body Axilrod-Teller C-9/R-9 term only increases the repulsive error. Our conclusions based on extensive solid state and molecular electronic structure calculations are particularly relevant for condensed phase van der Waals systems.
