If you want to have a cue made, then have one made. Any cue maker, here or anywhere, will be (or would have been) happy to make you a cue with no ivory in it. Many of these guys offer ivory as an option, but that doesn't mean they're pushing the stuff, or actively seeking to sell it to anyone they can. It's an option. If you say, "I'd like a cue made with these material & theses specs, I don't want any ivory involved", you'll immediately have a cuemaker that is focused on your desired specs & materials, and how they can be made to interact to create (1) the cue you want, and (2) a cue that reflects their build methodology. End of story. There's no need to demean the principles of these gentlemen as if they were actively, premeditatedly, aiding & abetting in a criminal act.
