Goes without saying. For a gov't to actually be 'of the people, for the people, by the people' it must exist only at the sufferance of the people. Which means if they can't remove it, then it's not 'for them'. Normally we can remove gov'ts without bloodshed or the like, but given enough time history shows that SOONER or LATER, a gov't will come along that doesn't want to be removed. Might only happen once every few dozen generations if you're lucky but when it does the people must have the means of resisting that gov't.
