If you really want to go down this road, I think you ignore the role of gravity at your peril. Both the potential energy stored up by lifting oneself from horizontal to standing, and the kinetic energy released when one's structure is undermined and one falls down.
Kinetic energy generated from dropping one's weight is still kinetic energy. And when dropped through a broken structure could result in a throw or takedown. So yeah, gravity only works when something is falling, falling is kinetic energy as well.
