I very much see your point, but here's something to consider. I know the discipline of scratch DJing is a lot more demanding beyond a regular mix DJ's requirements for the style, much of it is also done for the sake exhibitionism to demonstrate highly co-ordinated precision like dexterity with sounds and music etched onto a disk of plastic/vinyl record. I'm not about to get into how someone should mix and what justifies talent. But the term DJ does originally mean "Disk Jockey". The vinyl record being that "disk". Many DJ's today don't even use a "disk" of any kind, mainly because it's often redundant against the back drop of what a lot of modern technology that can be used does in terms of mixing music without music needing to be on a physical piece of tangible media for direct hands on manipulation like a vinyl record. But, it could be said that in the purest sense you are part of the few sub groups that are still actually using the original form of "disk" (as in the vinyl record) as part of your craft that led to the coining of the phrase "Disk Jockey". So in a sense you are still literally closer to being a "Disk Jockey" then many others actually are these days. Without that direct hands on interaction with the "disk" of plastic (the vinyl records you manipulate directly with your hands which holds the sounds of your choice on them for cutting up and scratching) and the "disk" player (more than likely a direct drive vinyl turntable for spinning and mixing the vinyl records on) you wouldn't be able to hone and eventually skillfully do what you do. What you do being extreme high speed "disk Jockeying" is an essential part of your scratch mixing craft. But after all is said and done, if you prefer being called a turntablist I can dig that.
