Alabama has legal spear hunting, and it would probably be the likeliest place to host stone-tipped spear hunting with a film crew.
In Queensland, Australia where he is based, it's illegal [1] to hunt anything which isn't feral or an invasive species of hare or deer, which are pretty hard to find, especially on small plots like the one he owns.

But yes, while there are feral pigs in QLD, it's a bit much to expect him to hunt them with a stone-tipped spear just to appease some random naysayer on the internet. I mean, the guy builds a tiled-roof house with chimney and underfloor heating using nothing but the stuff he pulls from the forest by hand, and somehow that's not enough - apparently he has to risk his life attacking a feral pig with stone tools to get 'cred'...
If he went hunting instead, he probably wouldn't have time to build huts and farm plots. I doubt he'd have much of an audience if his videos were about stalking rabbits in the bushes with a spear in his hand.
In most parts of the world, hunting with stone age implements would be illegal and at the very least it's (arguably) unethical because it would put the prey animals through unnecessary suffering.
Yeah, hunting was an important part of stone age hunter/gatherer culture but this guy isn't there trying to survive with stone age tools. I'm sure there are hunting videos in youtube if someone enjoys watching that instead.
