"I support individual freedom -- the libertarian philosophy -- and I certainly
believe governmental power has become too immense."
You, Sir, are no libertarian in this respect.
"This said, however, every society -- with or without formal government -- must have some rules to operate successfully."
I wish the government would operate under the original intent of the 4th and 5th amendments. The Courts have corrupted its meaning.
"but the courts -- the final arbiter in a democracy -- have upheld their validity."
Let's look into that...
Here are some snippets concerning the Supreme Court being the arbiter of the meaning of the
Constitution. The last two are from Jefferson.
"When any court violates the clean and unambiguous language of the Constitution, a fraud is perpetrated and no one is bound to obey it."
- State vs. Sutton, 63 Minn. 147, 65 NW 262, 30 L.R.A. 630 Am. St. 459
"But the Chief Justice says, 'There must be an ultimate arbiter somewhere.' True, there must; but does that prove it is either party? The ultimate arbiter is the people of the Union, assembled by their deputies in convention, at the call of Congress or of two-thirds of the States. Let them decide to which they mean to give an authority claimed by two of their organs. And it has been the peculiar wisdom and felicity of our Constitution, to have provided this peaceable appeal, where that of other nations is at once to force."
--Thomas Jefferson to William Johnson, 1823. ME 15:451

"You seem to consider the judges as the ultimate arbiters of all constitutional questions; a very dangerous doctrine indeed, and one which would place us under the despotism of an oligarchy. Our judges are
as honest as other men, and not more so and their power is the more dangerous, as they are in office for life and not responsible, as the other functionaries are, to the elective control. The Constitution has erected no such single tribunal, knowing that to whatever hands confied, with corruptions of time and party, its members would become despots."
-- Thomas Jefferson, September 28, 1820
