Can't remember where most of my stuff came from, I'd be willing to bet it was captive bred (other reefers tanks)... a few pieces from stores that came on frag plugs, not sure if those are captive mariculture from overseas or something that was done here at wholesalers...
however while you can get on your high horse about being captive bred, there is another side to wild caught. If its from places that collect responsibly (i.e. don't go in with a crowbar destroying a bunch of corals just to get one timid fish) you could actually be helping the reefs by buying wild (or maricultured) caught stuff. Simply put they don't see much money where corals are, by injecting your money into their economy (even if it gets split 6 ways to Sunday), which that can use to make sure that their resource stays viable, to protect against poachers, etc... however its their waters, their resources so they need to understand what they have and ultimately they make the decisions.
As it stands the largest issue facing these islands is construction... coral makes a great component to concrete mixtures, it's available, abundant, and cheap as snot (compared to shipping it in), what are you going to tell them? Stop building? If they find out there is a viable economic resource they might be less likely to strip mine all for the components to build on land... if you boycott all wild caught products you're basically telling them that there is no economy in keeping the coral reefs in tact and healthy and your "good" intentions actually have bad consequences. Eco-tourism is great, but you can have both eco-tourism and healthy collection of corals.
While most of my stuff in my tank is from other tanks, it's mostly because I'm a cheap booger

Arguments of fuel cost to fly them ... irrelevant simply put planes don't fly with just corals, planes with people fly out of those regions, corals simply ride in the cargo hold if there's room.
