While I see your point, I respectfully disagree. At the risk of being trite, I offer a couple of famous quotes as counter-examples:
"Give me liberty or give me death." -popularly attributed to Patrick Henry
"With hearts fortified with these animating reflections, we most solemnly, before God and the world, declare, that, exerting the utmost energy of those powers, which our beneficent Creator hath graciously bestowed upon us, the arms we have been compelled by our enemies to assume, we will, in defiance of every hazard, with unabating firmness and perseverance, employ for the preservation of our liberties; being with one mind resolved to die free men rather than to live slaves." -Declaration of the Causes and Necessity of Taking up Arms, Thomas Jefferson and John Dickinson
These words, combined with the silent statements of countless people who have given their lives to preserve others' liberty, I think this speaks well that liberty is, at times, more important than life. And it is easily inferred that life, without liberty, is not worth living.
And while it may be perfectly acceptable for some to live life with only the hope of future liberty, as this is of itself an exercise of liberty, it is not acceptable for those who concede their liberties to acquiesce to the concession of the liberties of those who do not.
