Why vinyl?
Let's just stick with that fundamental and what first comes to my mind ....
All else held equal, it's the sound quality.
What else held equal? E.g., $500 turntable/cart vs. $500 CD player.
Yes, some poor pressings of LPs will have surface noise, and that can be distracting. Is the better LP sonics (vs CD) worth the "cost" of that same LP with background, low-level "krrrrrrrhhh" that you hear between tracks or in quiet passages?
That noise may go away with another pressing, a better 'table, cart or stylus. And hence you enter another aspect of "Why Vinyl?" ... the hobbyist pursuit of perfection. But we're getting WAY off topic now!
