Most people will admit that laws are made up; that they are only good insofar as they produce a good society; that laws serve society, rather than society existing to serve law. Money is a little harder, but IME most people eventually acknowledge that the value of money is simply that we all acknowledge it has value. Whether people admit that nations are "made up" depends on how you press the point. That the precise boundaries of nations are a product of messy history rather than some ideal truth, most people will admit. But most people will push back if you insist on a broad sense of "made up"; for example, that no privilege ought to be given to "what's good for the country" in national policy, but only what is good for humanity, is a fairly unusual position. Consider Kennedy's famous line, "Ask not what your country can do for you; ask what you can do for your country". To someone who thinks countries are made up, this is nonsense. Countries are valuable if they serve humanity, not vice-versa. People are least likely to admit that their own religion is made-up; almost all religions claim legitimacy by asserting they reveal some sort of fundamental truth.
