  In a recent article [R. Bombin, F. Mazzanti and J. Boronat, Phys. Rev. A100,
063614 (2019)], it is contended that a two-dimensional system of dipolar
bosons, with dipole moments aligned at particular angles with respect to the
direction perpendicular to the plane of motion, featuring a "striped"
crystalline ground state, in turn undergoes a Berezinskii-Kosterlitz-Thouless
superfluid transition at low temperature, making it a two-dimensional
supersolid. We show here that the results provided therein, obtained by means
of Quantum Monte Carlo simulations, do not actually support such a conclusion.
Rather, they are consistent with that expounded in our work [J. Low Temp. Phys.
196, 413 (2019)], namely that the striped ground state is insulating (i.e.,
non-superfluid in the conventional sense), essentially behaving like a system
of quasi-one-dimensional, parallel independent chains. We attribute the
incorrectness of the conclusion reached by Bombin et al. to the very small
sizes of their simulated system, which do not allow for a reliable
extrapolation to the thermodynamic limit.
