That's where proper institutions and planning come into play. Yes, one human Great Leader doesn't scale. However, an institution that plans ahead and inter-disciplinary teams and honest planning for the situations within its purview, and then activate them when needed, that can scale.
That's exactly what Trump dismantled, in the form of the pandemic preparedness office. There are lots of non-political agencies that do their job and do it well because they're run by experts in the field rather than political appointees. Or, rather, that was the case until Trump decided to politicize them, too.
Good government is hard to scale, but it can be done. Abusive government can exist at any size.
(The absence of government lasts for about 15 minutes until hierarchies start to form on their own and some gang leader starts playing king of the hill.)
Government largely isn't preventative they are reactionary in most things. Humans are the same way.
Everything is politicized because it is about power. Those who want to wield power over others are controllers.
I am not interested in the garbage governments that Democracy produces. Democrazy is 51 wolves and 49 sheep voting on what is for dinner. We are all slaves to the state and are born into it, literally nothing about any governments of the world is voluntary. Every law we have on the books is backed by threat of putting someone in a rape cage AKA prison(which doesn't rehabilitate anyone to put them through trauma) or backed by the point of a gun because "I said so".
Trump should dismantle everything he can, he should sign an executive order today and permanently eliminate Presidential elections, ban them from ever happening again, and resign as President. Everyone in the FBI/CIA and all these psycho control groups should be immediately fired as they are all unelected. If they are so important they can be elected and held to account.
