Another way of putting this is that these corporate welfare reforms are about half as good as preventing their births, or better, for their welfare. So, corporate welfare reforms over a region (a country, a US state, a province, the EU, a continent, the world, etc.) would be as good as cutting present and future factory farming in that region in half or better (in welfarist terms, ignoring other effects, assuming no new lower standard farms under the reform scenario, etc.).
