Well, despite your protestations, it's my considered opinion that Nikon never wanted to make DX cameras and lenses in the first place. They did so because for a long time it was the only way to make a DSLR at a consumer saleable price point, and they continue to do so for the similar reason that there are people who want the smaller, less expensive bodies. This is my opinion, and it's one I've held since 2003 when the first reasonably accessible price DSLRs first appeared.
There is a place even in an FX system for a DX body too ... speed, more reach with a telephoto, etc. DX and other small format cameras are really best at telephoto use because they net more DoF at a given f/number.
If I were shooting with Nikon gear, I'd buy an FX body and FX lenses only. They're what Nikon wants to make.
If you want APS-C compactness, Fuji and Pentax do a better job of it. The whole reason to buy Nikon lens mount is to have access to Nikon's lenses, so if they don't make the lenses for what you want, why go there?
