  It is now well-established that mechanical equilibrium in athermal disordered
solids gives rise to anisotropic spatial correlations of the coarse-grained
stress field that decay in space as $1/r^d$, where $r$ is the distance from the
origin, and $d$ denotes the spatial dimension. In this note we present a
simple, geometry based argument for the scaling form of the emergent spatial
correlations of the stress field in disordered solids.
