Tax should be used for a limited number of things, basically to protect the individual from the masses, pay for the police, pay for the military, pay for the judiciary and pay for public health. This document is ambiguous about public health. Basically public health, I believe, is about communicable diseases, not cancer, and so on. That is what the state should pay for, nothing else. The only role of politics and politicians is to guard the guardians of society, the police, the military and the judiciary.
Someone has to guard the guardians and that is the role of politics.
The danger is that many of the projects have hidden agendas. Government is not a unified entity, there are all sorts of turf wars going on. If I am e-trading with you, I do not know who you are and you do not know who I am. We go to someone who guarantees our legitimacy. Maybe this is a role for government acting in this way, but if government insists on looking at what you are doing then you are not trusted, so nobody trusts government.
