There's a huge spectrum of opinion between libertarianism and wilfully endorsing authoritarianism because you happen to agree with a particular policy. You don't fight a common threat individually, but the government isn't always the best organ either. In my country the pandemic response has primarily been an exercise in tearing up civil liberties (there's now permanent legislation against protests for example which I doubt could have happened without the climate of panic that the pandemic precipitated), enriching a self-serving sociopolitical elite with all kinds of unethical behaviour such as dodgy PPE contracts, and arguably failing anyway at preventing widespread loss of life despite the immense collateral damage. That's not even mentioning the devestating effect on generational inequality which was a terrible problem to begin with.

I'm particularly disgusted by the use of military-style behavioural psychology tactics against our own citizens to terrify people, I cannot conceive of the kind of person who'd think that's okay in a free country. The only thing we've actually done with any distinction is the vaccine rollout, which was excellent mostly because the government left the details alone and simply gave the existing infrastructure the resources to do its commendable work (I'm willing to be proven wrong on this, as my information is conflicting).

All the "all in this together" talk is complete crap in the cold light of day, sometimes collectivism is required but parliaments and certainly partisan politicians in a power-drunk executive branch aren't a good organ to do it with. We do not need to build a permanent surveillance state or other organs of tyranny to defeat COVID, nor do we need to build a society of mean-spirited, curtain-twitching moral authoritarians which will takes decades to undo.

EDIT: made some clarifications
