Plants require less land than animals. Shipping is quite cheap. Not to mention that lots of meat is shipped from developing countries to the West.
They require different land. Also it would be bad to add that much extra topsoil for produce considering we already use it faster than it is produced. It is efficient to have cattle.
You seem like a very communist, or at least central authoritised for an AnCap. I eat beef because it is one of the greatest foods. It doesn't lack amino acids, and taste better.
No, I have never expressed such desires. I'm making *arguments* as to why eating some things is bad and eating other things is good. I don't support government bans on meat.
