Physical laws do not have action-at-a-distance. Physics laws are about what happens at space-time points {local interaction}. Except for large forces, local interactions are approximately linear, allowing linear coordinate transformations and energy-momentum-field tensors. Spaces with local metrics include Minkowski space, Einstein space, and Lorentzian space.
Global physical effects are typically non-linear.
