Yes, it's "only" philosophy, but that doesn't mean it's utter BS.
Look we either talk about the exact pi, or not pi at all. In my computer there's no pi.
As for the alternative, at least he tried something:
"Fuller also claimed that the natural analytic geometry of the universe was based on arrays of tetrahedra. He developed this in several ways, from the close-packing of spheres and the number of compressive or tensile members required to stabilize an object in space. One confirming result was that the strongest possible homogeneous truss is cyclically tetrahedral."
