Dark Forest is not self consistent. Ability to travel implies nanotechnology which allows metabolize any resource which deterministically leads to expansion which leads to self-selection for fastest expanders which soon means relativistic expansion which is hard to observe since observation window is short while pre-expansive observers are extinguished. Alernative is that nucleation density is very low and/or (reaching the stage of) travel and expansion is impossible. This is consistent with what we see, so Occam's razor cuts Dark Forest.
