The source I cite for only 20-60% of GHG emissions being sequestered includes grass-fed beef. It seems like buying grass-fed beef is still environmentally unsustainable.
Your claims don't seem to match any of the evidence I've seen, but I'd be interested in discussing them further if you could provide sources.
As far as poor soil, a) current animal agriculture is mostly making use of usable soil & farmed crops, so this currently seems like a moot point, and b) this gets back to the above issue of being completely unable to scale. Unless you're being careful to only eat meat about once a month, I don't understand how the use of only poor soil is supposed to produce enough meat to feed everyone who would want it.
