Naturally there are no rights to anything other than your thoughts and ideas, and that does not include the expression of those two or the life that gives you the ability to have them. Every "right" we have in society, including your right to life, is created through common social standards within our society, and have to be protected by law, force or whatever mechanism is in place wherever you are. What's called your "god-given right" to life, liberty and the pursuit of happiness can theoretically be taken away by a simple change of government if it was to fall to a ruthless dictator. In this very nation, African slaves had no right to liberty or the pursuit of happiness. So I would say yes, you need some kind of social order to establish any kind of right beyond the right to possess your thoughts during your life.
Your other questions are moot. You're not arguing rights, you're clearly arguing legalities between the government-given right to property and taxation.
As usual, the idiots come to advance a misnomer...
There is no social contract, which provides any right of any kind... all a government or any collective, which by virtue of it's means, which possesses the would-be power to do so, can do... is to extend a cultural privilege...
As is typical, at the root of the issue is the notion that the means to exercise the right, represents 'the right'...
Such is not the case... My rights are endowed to me by my maker... oka: Nature's God. Those rights are unalienable; meaning that no one but my maker who endowed the right to me, can separate me from my rights... Intrinsic in those rights, is my responsibility to defend those rights; and not only for myself, but for those within my sphere of influence (my neighbor) as well; to the extent of my means. And where I fail to defend those rights by failing to recogize and maintain that responsibility... where I concede the responsibility, I concede the right.
Where a human power usurps my means to exercise my rights... it is my duty to destroy that power, again, to the extent of my means; and if such effort results in my earthly demise... I died engaging in that to which I was rightfully entitled, thus I did with my rights intact.
Rights of social contract, are again, not rights at all... they are but temporal privileges; which as the idiot noted, are subject to change with the changing of the power that granted them.
