Heheh, this guy is hillarious ;)
Just because you can get roosters to screw a suitcase or pigs to hump a fake sows, doesn't mean it's a given, which you state, they can't, or at least have trouble doing even with all their fake gadgets.
I am stating that Pyrruss if he thought it necessary and worth the cost would give the elephants the space needed and as Africa has shown elephants do breed quite well. South Africa has gone from a population 8 k to 20 k in 13 years, just by banning ivory trade and protecting the polulation, though I'm fairly certain that it's easier to hunt the ivory than the poachers.
