Math? Why certainly. Let's do some math.
You have no right to do X. Other people have no right to do X. It can then be said, no person has a right to do X.
If you, nor other people has any right to do X, that would be expressed as 0 (zero) right to do X.
Therefore, you cannot aggregate a sum of zeroes, to try to create a positive sum, or take a bunch of people all of whom have no right to do something and create a right to do something, from a collection of individuals none of whom have a right to do that something.
Therefore, government can have no greater right than the extent of any of the individuals involved, since no person can delegate a right he/she does not possess.
Hence, Voluntaryism, is mathematically provable and government is not.
You're welcome.
