I can certainly understand both sides. I don't own a gun I can't shoot, nor do I own one I haven't shot, but some have just been fired a bit to enjoy, and then put away. Others have been nearly worn out from all the shooting I've enjoyed with them.
Almost all my guns are pre WWI era, and many tough to replace, but it's been more a case of condition that limits me shooting them, more than value. I don't shoot those guns that are really pristine nearly as much as those that have seen more use.
