The problem with the idea of "granted" liberty is that the agency that "gave" them is more than likely going to either take them away, or hold them for ransom. The only way to ensure the greatest freedom for folks is to recognize pre-existing natural rights (commonly referred to as "negative", as they don't require that other folks be stolen from or otherwise oppressed) and require any existing government to operate within strict guidelines in order to avoid treading on them.
Unfortunately, any time you allow a group of people to gather and maintain power, they'll do everything possible to grow it, and you'll also attract the absolute worst power-hungry rascals to those positions... folks clever enough to erode and evade their own legal limits at every opportunity. It takes a special sort of bastard.
Ergh. Politics. Many blood-sucking creatures. I think I'll go back to reading about cameras now and stop jacking threads.
