The primary (if not sole) function of the state is to ensure these fundamental rights are granted equally to all citizens. Both through the instruments of the law, as well as through military defense of the nation from foreign threats. This is my conception of the state and it's fundamental duties and responsibilities.
Further it is also my belief that any governmental actions that exceed these few, limited, essential functions are coercive and unjust by their very nature. To illustrate, consider the case of taxation. Outside of funding the few limited functions of government as discussed, what is the function of taxation? To force individuals to pay for collective, social 'benefits' that A) may or may not actually be beneficial to those individuals specifically and B) even if they actually did benefit them, they still may or may not choose to pay for those benefits. Thus, taxation is theft and destruction, at heart. Taxation to fund the few essential functions of government is theft that we just have to tolerate as a trade-off, because the alternative is even less tolerable (that being anarchy).
Now for some relevant quotes:
Government, at it's best, is a but necessary evil; at it's worse an intolerable one.
Chief Justice John Marshall:
The power to tax is the power to destroy
No matter how reasonable a position this is, regardless of how fundamentally humane a philosophy this is (at core concerned with human rights), invariably the most common objections to it are appeals to emotion such as "That's a heartless philosophy", or "You're a cold individual." It's been my experience that such objections arise from fairly unsophisticated thinkers who can't differentiate between the advocation of a public policy and private beliefs. That is to say, it's often assumed that since I'm against what is ostensibly forced charity (an oxymoron if there ever was one), through the instrumentalities of government, then I also must be anti-charity in general. Which is of course blatantly fallacious.
In addition, heartlessness is not wholly a negative quality when it comes to government policy. Government should operate through processes and systems that protect against things like human emotion. Rights, the government, the law, justice; these things should not be human personifications of a collective will. They are processes distilled from human tradition and wisdom which protect against human emotion and error (the most significant products of the 'human will').
