When you pass laws that can't practically be enforced, or that everyone figures the insiders/incumbents have already tilted in their favor with de jure or de facto immunities – such that they're only ever used unevenly against disfavored upstarts/outsiders – it erodes confidence in laws & law-enforcement more generally. Under a majoritarian system, even if >50% claim to want a law in polls or ballots, but far-more-than-50% of the same people (or even just: the relevant targets of the law) can flout it without consequences, that's typically a bad law.
