A CNC can do anything a 3D printer can, cost being a hinder to CNC. Remember, there are horizontal, vertical, and lathe CNC's. You can carve anything out of all three, granted you have the correct tool bits. I've been a CNC operator in 2 different manufacturing facilities making totally opposite products, with CNC and machining college under my belt also.
Here's an article comparing CNC vs 3D printing. Each has their own perks.

I just didn't think you could get the bit down 12 or so inches of titanium tube to customize the inside mm by mm. Or to navigate the inside curves of an S-bend chain stay. Just two examples.

It just seems like there would be some restrictions on what you could do. Now if you want all the detail on the outside, everything is easy.
