Many people swear their subjective experience of the music is better if not digitized. I'm not one of them, but I doubt digitizing vinyl is going to satisfy them. After all, why get the vinyl in the first place?
That's my point, I think what the parent is asking is antithetical to the vinyl experience.
That being said what I propose with 3D-printing is almost certainly what effectively happens with vinyls these days. I doubt music labels maintain a completely separate and parallel analog workflow in order to have "pure" vinyls at the end. Why bother when you can take the digital master and dump it onto the disk and nobody will be able to tell the difference?
