There are good reasons. The only two sensible ones are because you have a legacy collection, or you are collector and you want to seek out rare discs not available in digital form.
I have a large legacy collection. It is in good condition. I have bought very few LPs since the CD advent in 1984. I did buy quite a few discs though out of a large collection on eBay. This was from an estate collection of an owner who had superb equipment. All those discs were perfect and unblemished.
There are several issues about LP playing. Old LPs in general had superior manufacturing standards to most current offerings.
A turntable rig has to be to a very high standard and obsessionally set up. In addition handling and care of LPs has to be equally obsessional.
So, I agree that unless you are fascinated by the whole ethos of disc playing, have a legacy collection or want to collect rare discs, or music not otherwise available there is no pressing reason to get into LP reproduction. It is not something to undertake in a casual manner.
I own four turntables. All are vintage. Three I have owned for over fifty years, the other one, is a classic, that I restored after buying it cheap on eBay parts or repair.
It is complimentary to my reel to reel tape recorder collection and associated noise reduction units. It forms what I call the museum aspect of my system.
This is important, as playing equipment over a half century old in optimal condition shows actually that the progress we have made has been largely on convenience.
There is one other aspect to this, that in many ways recordings were far better engineered back then compared to now. Recording was a career with job security. Firms like EMI and Decca kept highly competent teams together over a long period of time. The results show.
I have astounded many visitors with the superb audio quality that can be obtained from these vintage pieces. These are items for view only, but to still savor and enjoy.
Many exotic modern efforts are full of the flavor of the day audiophoolery, whereas back then it was true research and engineering driven. It was not driven by over active imaginations.

Disc reproduction is not plug and play. It takes experience and careful set up to get really good results. If you blindly forge into it, the overwhelming odds are for a poor result.
