It is a problem, I agree totally and something I’ve been looking for since getting the S4 a year ago. In particular trying to find digital versions of older, deleted vinyl is a problem. Thankfully some labels (who are still going that is!) appear to realise this and are releasing digital versions however they are often quieter due to being mastered originally for vinyl. Discogs can be useful for finding vinyl replacements as is HardToFindRecords (UK) but you may pay quite a bit for them. I’m in the process of digitizing my vinyl collection and it is a long, drawn out affair plowing through 5k+ records.
