There's high fence, and then there's high fence... and JJHack doesn't run "canned" hunts, so I don't expect he would endorse one.
There are really big ranches in RSA that are high-fenced, so big that they are no different than a low-fence operation. But the animals can and do reproduce, populations increase, and the need for thinning the populations becomes manifest. This is a far cry from "canned" hunting, where the animals are confined in a small space, or released from captivity in a known location immediately before the hunter starts "hunting".
If you think such a hunt is not fair chase, then consider how it's materially any different from the hunting done in East Africa 150 years ago, when the plains absolutely teemed with game. If the property is large enough (and I had the money at hand) I would have no problem taking on a hunt like that.
