Hypotheticals are valuable when forming policy, because they point directionally to incentives and potential counterfactuals. Nobody has yet had to take arms up against a potential tyrant in the US (claims of the southern states during the civil war aside) but one could argue that the reason such tyranny has never been attempted in the first place is due to the deterrent of the 2nd amendment. Just because we can't point to a concrete example which proves the necessity of the 2nd amendment to prevent such tyranny, doesn't mean it would be a good idea to repeal it on the grounds that we do not know if those hypotheticals would actually manifest. Similarly, having policies for voting which prevent coercion seem sound despite the fact that it's currently unknowable if in the absence of those policies we'd see an electoral impact due to such coercion.
