If you’re producing 54% of your consumption using 70% of your land area, even disregarding what land area is actually suitable for agriculture and evicting all other users from the land, converting all land to agricultural use still probably isn’t going to get you to domestic production of 100% of domestic consumption.
If you evict everyone, then consumption falls to zero and you have a surplus = success, in their stupidly short-sighted terms.
