I’d be fine with there being a rule that you can only kill/eat what you’ve raised yourself. No selling.
I think that would make a lot of people think twice, if the taste is worth the effort.
The problem there is people in cities could not do it, in many cities it’s illegal or not feasible to raise chickens or goats, or to hunt or even trap.
I mean I agree, I prefer rural. I’m told however that nobody else does and that is why cities exist.
I don’t think most of those people are going to go for that rule, you’d likely have black market agriculture happening, and that hasn’t been working so well for drugs these days. Gonna get turkey laced with fent and shit lol. Good luck with that though!
