Does a wolf have the natural right to defend its home from another wolf? No, it's just nature.
You just rebutted your own rhetorical question. The wolf has the
natural right (as it were) to defend itself and it's den against other creatures. This doesn't guarantee success, however. Man is also part of nature, but his natural intelligence (over animals) allows him to make and use tools to defend himself against predators. He has the right to his own life, to defend it just as the wolf does, and the right to use any tools for his own survival.
Man is also the only creature who devises his own rules and submits to them voluntarily for mutual benefit. Unlike wolves, men must be reminded of the difference between man made rules and those of nature or God.
endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness
There is no god. Now what do you do.?
Whether you believe, as our forefathers did, in a deity or, you follow the "natural rights" concept, our laws and concept of government favor the rights of the
individual over the powers of government.
Our government, and thus our laws, were forged on the hard anvil of experience with Kings, Viceroys, Governor-Generals, corruption and tyranny. Our constitution came about to
prevent government from being the
master of every man instead of being the servant.
That man is sapient, with intelligence to direct his own destiny, each man has a right to his life, to pursue his happiness, and a right to liberty.
A man's life is his own and he may not be forced into servitude, involuntarily conscripted, told what trades he may enjoy, prohibited in his associations nor required to attend a church, a meeting or any other gathering.
Liberty is beyond "freedom" as freedom denotes merely a lack of coerced actions, while
liberty is the power to act as one chooses. It means people can live free, talk free. Come and go, buy or sell, be drunk or sober, however they choose.
This is the background and framework against which our Constitution and many of our laws were written. A read of the Constitution and BoR shows prejudice in favor of the liberty of the individual - requiring the government to justify its intrusion on a man's liberty - versus the absolute authority over citizens.
Given that our constitution seeks to permit the broadest liberty to its people, that the constitution was written following years of war for our independence, it would seem more than
merely inconsistent that the right to arms would be enjoyed only by (state) governments, when those arms were indispensable in the fight for independence.
Our constitution does not
grant a thing in the Bill of Rights. Each Amendment declares that the right exists, that it exists when a person is born and that government may not deny a person the right by any laws, decrees or pronoucements.
