The point is that energy is not the same as the ability of a system to do work. Work is just a part of the total energy balance of a system. In a isolated system of classical point particles in thermal equilibrium all energy is locked in the kinetic energy of the particles, but the kinetic energy of every particle still contributes to the total energy of the system.
Agreed.
