I would personally rather see much stricter rules and regulations on animal welfare and industrial farming, combined with an import ban on countries that don't have similar rules (perhaps with a mechanism where individual producers in those countries can apply foe exception to the ban if they can prove that they are up to standard). And then let producers compete freely under these new rules without additional taxation or subsidy. Of course the big downside is that this would effect the poor to a much greater extent, since they are primary purchasers of this cheaper meat that would disappear from the market.
