I still take the view that the problem is caused by breaking up the analogue signal into billions of tiny fragments that cannot be correctly reassembled. This is the origin of dither and clock error. It would seem no-one can solve this - the issue is 40 years old and there is no solution in sight apart from accepting the problem and reducing it by engineering.
As to starting vinyl from scratch, many older audiophiles are disposing of vast numbers of vinyl albums, either on downsizing or when their ability to listen comes to an end, one way or the other. There is a plentiful supply - that's where I got most of mine from. Many are near mint because we cannot play all our LPs very often and we look after them when we do.
I have also written that many audiophiles obsess about record-cleaning to an unnecessary extent or even ridiculous extent.
