  We propose a simple model of a two-dimensional ``locally smectic
superconductor'' that exhibits power-law non-linear I-V characteristics with
different powers for current applied in two orthogonal directions. We discuss
the potential relevance of this model to recent experimental findings on
interfacial superconductivity in EuO/KTaO$_3$(110) (Nat. Phys. 20, 957 (2024)),
where the apparent critical temperature ($T_c$) has been shown experimentally
to depend on the current direction.
