Couldn't "capitalism" or "market based" system mean any system exists where people generally are compelled to perform for each other based or some sort of offer acceptance and consideration?
This could all be based on asking whether or not someone is for "human rights" or "freedom".
A market based system is at least in theory based on mutual consent, but capitalism I would understand as involving the use and investment of capital as central to economic activity (though that definition would describe a great many things not usually thought of as capitalism).
