So you're saying the lockdown is a pretext for a technocratic and totalitarian coup against free-thinking peoples. That sounds like a paranoid conspiracy theory to me; more precisely, it's a story cooked up in right-wing media to retain the interest of their viewers and to intensify their hatred of the liberal opposition. Conflict sells even if it makes society more tribal and self-destructive.
Don't get me wrong: I really do happen to loathe medical doctors on average. I wouldn't use the word "scientists" in scare quotes as you did, since it's certainly a real science. But I wouldn't put such a technocratic conspiracy past the personality of many doctors. Those are some very arrogant, scientistic individuals who likely think they ought to be ruling the world, because they flew through medical school and are therefore superior specimens.
However, you're ignoring the weakness of left-wing parties (from a realpolitik standpoint), namely their femininity. Left-wingers (I'd call them secular humanists) consist largely of women and effeminate men. That's why they fail so often when confronted with the much more monstrous (nakedly psychopathic) right-wing parties. Feminine individuals want to avoid fights and want to compromise, heal the world, and so forth. Even if Democrats, for example, wanted to establish a socialist tyranny, there's no chance they'd be heartless enough to go through with such a coup. They're bleeding hearts, not heartless Machiavellians.
Again, your story sounds more like an exercise in whaboutism, like a distraction from the fact that the conservatives were the ones who literally tried to carry out a coup in the US just a few weeks ago.
Perhaps there are disastrous unintended effects of liberal policies, but your conspiracy theory goes much further than saying that.
