4. if strict rigors are applied to husbandry techniques, even if these technological advancements don't happen (unlikely)you'll still have a live animal to extract enough genomes from it for a clone. also, reintroduction from traditional cb has been successful in the past. not highly successful, but it is possible.

I'm sorry, but this is even more ridiculous a justification than the "possibility" of reintroducing captive animals from private keepers' collections.

Again, governmental agencies and conservation groups will never utilize animals from the private keeper sector because of the ambiguity of their origins, among other risks that could prove devastating to a population (i.e., diseases they may be harboring, etc.).
