I think the origin of all this clamour for tonality is not so much the need to sense a relationship to the tonic, as a need for familiar chords: let us be frank and say "for the triad"; and I believe I have good reason to say that just so long as a certain kind of music contains enough such triads, it causes no offence, even if in other ways it most violently clashes with the sacred laws of tonality.
