Hypothetically, Zuckerberg is going to have family members of the people guarding him locked away somewhere as hostages with other people set to guard them with the original guards kept out of direct communication with anyone but Zuckerberg or his trusted lieutenants. Cousin Eddie isn't going to take over when it means Cousin Franny gets to live less than or equal to how long Zuck lives.
Horrible? yes. Rational? Also yes.

Hypothetical fantasies aside, they can only do those things after civilization collapses, and by then it’s too late. Power in the absence of civilization doesn’t depend on the ability to delegate everything, it depends on the ability to beat someone to death with a jawbone.
An actual tyrant requires a government, and it would be quite some time after a traumatized populace stopped just trying to survive day to day for such high level organization to re-emerge. On all likelihood, generations would need to pass.
