I am sure that I have not talked to everybody, but they have had some success with culturing in the ocean and greenhouses. Some have tried to culture them in facilites with substandard lighting, filtration, etc... something similar to what a hobbyist might consider a softie tank. These mostly failed.
I just want some A. Palmatta in my home since I saw a magnificent piece snorkeling in Florida once.

It will probably never happen, but if it does, I would spread it around for free to anybody who could keep in just in the hopes of it surviving. I once saw a piece at an aquarium in St. Louis and it was actually quite nice under reef lighting - purple with a blueish tint. They look just brown in the ocean at 6500k. I would put 1000w MH over these at whatever spectrum necessary to get them to thrive. I would make a species only tank. I would make this like 2% about me and 98% about the A. Palmatta. C'mon Florida, send me a frag!
I seemed from talking to a few that the disease thing is mostly a red herring. Politics is the largest issue - no ship means no ship, right? If us hobbyists can figure out most diseases, quarantine, etc. then so could an actual pro.
I have had acropora spawn in my tank. What if a hobbyist could get an A. Palmatta to that size, transfer it to a solid AQ place (along with the experience and knowledge of how to keep it in captivity) and have it spawn there with all of the resources of the ocean. This is likely how this hobby helps the world one day... probably just not in my lifetime.
