I'm not actually sure this makes the metaphor less applicable. Network and position matter for both, but the point values in Chess serve to describe the relative value of each piece in addition to that, while the lack of differentiation between pieces in Go means that even more attention must be paid to the network and positions. It is not that network or position don't matter in Chess, but that only network and position matter in Go.
