If digital was so arse-awfully perfect then why are there still terrible CD players around? The bottom rung CA players are awful. In 2003 I bought a NAD C521i CD player and it was one of the worst things I heard - sibilance galore and a narrow soundstage.
Because like anything else, getting the absolute best from it takes care, attention to detail and money, particularly with regards to the analogue section after the CD, HDD or whatever has been read. And yes while some digital players of any persuasion can sound lifeless and dire, I'll see (hear?) the worst digital player you've ever heard and raise you any number of goddamn awful plastic midi system turntables from the 80s and 90s that should never have been allowed to play a record. Oh and just about everything currently made by Steepletone and Crossley.

As soon as you add anything analogue into the recording chain or are converting an analogue master tape then loss is inevitable.
That's definitely true at least. But I'll add to that, there exists no method whatsoever to copy and mass-distribute analogue audio in a way that doesn't lose quality. So at least having converted it to digital as far up the chain as possible, you now have a constant you can losslessly distribute, ad nauseum, potentially forever.

At its most simplest you can take a pure sine wave and dice it as many times as you want as you would if converting to digital, you are never going to get that pure sine wave again, although you may come close the higher the sampling frequency becomes.
No that is incorrect. Nyquist-Shannon theorem proves that
16/44 has the potential to re-create anything you or I can hear, perfectly. Feel free to diss it, but it's a proven scientific theorem, essentially dating back to 1928, not some crazy wakjob's theory who's trying to bolster the defence for CD (difference between a theorem and a theory). You've been reading too many articles showing pictures of step-ladder sine waves and listening to too many marketing spin doctors tell you that HD audio sounds better than CD because the sample rate is faster.
