Are you saying that 10% of an economy is vital goods and the other 90% is not? Not that I have any numbers on this but 10% seems low to me.

10 % isn’t based on anything but let’s imagine: 2-4 % military 1 % communication infrastructure, media and unbiased information 2-4 % healthcare 2-4 % food. You quickly get to 10%. Too big and you loose the benefit of free trade.
