I both collect and shoot my Cap and Ball revolvers...
If I buy a used Cap and Ball revolver, that is in pristine condition, I may not shoot it, especially if it is a second generation Colt.
I have enough shooters as it is.
I have a Cimarron Paterson that is in mint, unused condition, which I won't shoot. If I find a Paterson that can be used as a shooter, then I will shoot that one.
Some people have a had time understanding this. I like to keep some firearms in mint, unused condition, especially if I have another as a shooter...!
