You can always mimic the sound you'd get from analog media using a CD the same way you can emulate a CRT using a modern HDR high-resolution display with fidelity well beyond our ability to differentiate them. With a high-end GPU we can do CRT emulation in real time.
That's not what the person you're replying to is talking about though - they're stating that the motor that spins the disc is causing interference in the signal.
(I have a hard time imagining that it's worse than the electric motors used to drive vinyls or cassette tapes, but if it's there it's there I suppose)
