If the landowner gets the hog control permit, all of those control methods are available.Hunting doesn't IMO, hurt the control issue, not allowing hunters to use known means, like at night with bait, to hunt them does. As to the trap and release, that is not hunting, and since it is illegal it will, and does, still happen. Most times, sounders stick together, so while a sounder may be moved to a less pressured area, they don't create more sounders, at least any more than they would have anyway.
The illegal translocation is the major problem, and by allowing hunting, it just increases the problem.
