Functioning democracies do yank out their elected representatives. Not randomly or even arbitrarily of course, but when they step egregiously out of line. Votes of no confidence, recall elections, impeachment, general strikes demanding resignation, and a smattering of other measures are crucial checks on the abuse of power. Electing someone to be untouchable for a set period of time is a recipe for malfeasance with examples going back as far as the invention of the term "dictator".

Re-read the comment I replied to and check if that comment was referring to everything being great already because those systems are in place or if they were calling for some kind of ad-hoc popular vote at any point during a mandate based on not liking the policies, rather than for egregious actions as you described. Your reply is theoretically correct but not what I replied to.
