You have to also take into account Long Term and Short Term thinking. Not only are we playing a Prisoners’ Dilemma but most of the population is thinking about a value function that pays off in the Short Term (it’s definitely true about events outside the population’s expected lifespan, but also is true within a single lifespan). In the Long Term all of our needs are relatively aligned. There are pivotal points in history like the signing of the Magna Carta at knife point, rather than yet another relatively-shallow regime change, that are thinking about the value function in the Long Term. There will one day be an iteration on democracy that solves the Byzantine Generals Problem. Where the “failures of communication” are caused by Short Term thinking.
