I may have got the wrong end of the stick on what Oyster was trying to say?
I suppose my concerns are more to do with one, overarching institution, dictating policy.
This current push to have the WHO be able to enforce rules, effectively being above governments, seems particularly disturbing.
Here's a brief but interesting article on it:

And as for Covid ... lets not forget that when the American Government were trying to enforce mandatory vaccinations for federal workers ... for some reason, Congress was exempt. Its one rule for 'us', and a totally different set of rules for 'them'.
Having multiple institutions/seats of power, as opposed to one, master dictatorial organisation, would seem to offer more chance of being able to avoid the one, corrupt power having total control.
