You're conveniently ignoring all the wild shadow docket decisions in Trump's favor with no provided justification. None of that sets a precedent.

There's also a giant bloody spectrum between 'policy that had a bad outcome for someone (hint: That's every policy)' and 'blatant pay-to-play corruption and criminality and treason' when it comes to that immunity. The court, of course, went all in on enabling the latter, instead of finding any kind of rational ground, because any rational ground would have put Trump in prison.

By failing to give any qualification of what the fuck an official act is, they've given him blanket immunity. And blanket immunity for an executive means that the constitution is as good as a piece of toilet paper. There are no consequences to him violating your rights.
