Why is it reasonable? Because distortion is cumulative. There's distortion in the recording mike, cables, recording preamp, disc/vinyl mastering, your sources, amps, cables and speakers. It's like asking "why clean your eyeglasses if your windows are dirty?".
Speaker distortion a fact of physics life. I second the notion - buy with your ears (and within your credit limit, of course), and not with the back of the brochure.
