It's the paradox of all democracies. The freedom of the people to change any aspect of their society, including the founding documents that create it, mean they have the freedom to give away their freedom. Giving away freedom has always been part of the constitutional contract. The idea is to curtail what freedoms we curtail, but there is no way to mandate it without fundamentally curtailing the fundamental freedom to choose what can or can't be curtailed.
If it sounds like I'm looping, that's because that's what paradoxes do.
