Should people with no turntable or reel to reel be considered audiophiles?

Perhaps sound quality in cars is underrated. Modern automobiles should have a reasonably good signal to noise ratio with the windows up 🔝 ROLLS ROYCE would be even better, especially with the oil-filled suspension system for mechanical isolation. Battery power, good acoustic space and crossover-less speakers - Voila! Audiophile grade SQ.

Of course. It's a ridiculous, snob-driven question. The satisfaction for the audiophile is the sound of his or her best liking, not the media he or she plays to achieve it. Having been through and gotten rid of many tables and one hundred times as many albums, I find good quality digital sources played through with my S.E.T. or Push-Pull amps to suit just fine. This coming from the previous owner of a very high end salon that carried both analog and digital.

Just fine is not good enough for many of us.

We want as good as possible for a given amount of $$ investment.

Yes.  That like asking a McLaren owner if a Porsche is a sports car.
