So, you also need a system of determining succession of trusted individuals that not only selects humans who can be trusted, but humans who understand the challenge of defending the purity of succession procedure. All it takes is one corrupted transition. One person submitting to a little nepotism, to poison the entire system.
And of course, wherever you create a centralized repository of power, whether it's a hoard of wealth, a position of authority, the head of cult following, or admin access to a database, you immediately create a game for power hungry people to figure out a way to corrupt the systems in place that prevent abuse of that power.
This is why so many people are working towards decentralizing systems of power. Hell, even the US constitution is an instantiation of that, with the established separation of powers between the 3 branches of government. While we recognize that centralizing all governmental power in a single position can lead to incredible efficiencies if you get the right person in charge, it is also incredibly fragile and dangerous in the long run. We accept the inefficiencies of decentralized systems in exchange for long term stability and anti-fragility.
