That's why we have battery farms in the first place - to produce more of the product than we would otherwise be capable while sinking corn. That's why we feed cattle grain, btw, corn is one of our hardest worked crops. It's cheap.
While pasturing cattle is not necessarily a regenerative practice, when it is done for that purpose it's not done solely for livestock management - but for the benefits that regenerative ag grants to other farm enterprises which also contribute to the carbon budget, if you will, of any farm. Livestock can till, livestock fertilizes, livestock manages your seed bank cutting out petrochemical herbicides... and a healthy relationship between ag and the farm environment cuts down on petrochemical pesticides. It's not an issue of just changing feeds - though there's no reason that pastured cattle couldn't be or wouldn't be fed supplemental grain.
etc etc etc.
And if grass-fed cows aren't responsible for methane emissions, how it is that, as we have less and less grass-fed cows around the world, there have been less and less methane emissions?

This is also the argument I used in the video.
