1: Vinyl digitized to a mininum of 24/96 LOSSLESS on a high-quality studio-grade ADC (soundcards are NOT good enough) is indistinguishable to the phono source itself. This is not just based on my hearing (I would not trust that alone) but on that of everyone we did the test with. I am talking about comparing to vinyl on SME30 and above type of tables. All the euphonics, "air",depth, and so one, transfer perfectly.
This still does not answer the "why" question...leading to,
2: We have very rare and often irreplaceable copies of vinyl recordings. We want to archive them but still enjoy playing the music whenever we can. Hence the transferal to digital...where we, by hand, remove egregious pops and clicks but otherwise leave the recording alone. If we are going to archive the irreplaceable records, then why not ALL the collection?
3: A music server of high quality is very very convenient to use; we have our systems setup to be controlled by an Ipad. You sit in your listening chair and choose from the hundreds of thousands of songs on your list. Now, music servers are not perfect, nothing is, but the servers I build have made folk sell off their dCs transports and uber clocks! There are many guys out there than can build them just as well or,perhaps, even better! (Ego alert..no no they can't do it better!!)
4: I am getting old, getting up every 10-15 minutes to change a record over, when I have totally automatic abilities in my server, just seems nuts to me. If I was tied to the ritual of putting on the record, that would be one thing, but I am not a ritual sort of guy. What I am is a lazy sort of guy....
