Generic emergence of objectivity in position basis

The emergence of an objective classical world from the quantum behavior of microscopic constituents has long puzzled physicists. The quantum decoherence paradigm-particularly through quantum Darwinism and spectrum broadcast structures-seeks to explain this transition within standard quantum mechanics. However, existing models often assume a preferred basis for interactions, an assumption that is not always well justified. Notably, classical reality manifests in the position basis, raising the question: is position fundamentally favored by nature as the preferred basis? I will present a simple no-go result demonstrating that interactions between internal degrees of freedom inevitably disturb spatial degrees of freedom. This unavoidable disturbance leads to the objective encoding of positional information, even in purely spin-spin interactions, reinforcing the privileged role of position in the emergence of classical objectivity.
