As has been pointed out here, with stats, there is no evidence that lockdowns actually make any difference. You are still pushing the argument that lockdown = fewer cases, which just isn't supported by the evidence.
Less intrusive, targeted measures would likely be no less effective while not causing the massive damage which these lockdowns have done and are doing.
You seem to keep conflating lockdown as a long term strategy with lockdown as a short term strategy. To argue that a lockdown has no effect on case rates (and thus healthcare demands and deaths) in the short term comes across as quite frankly as sticking your head in the sand. A set of less restrictive, more targeted measures over the long term (ie Swedish style) is obviously preferable, but when faced with the situation as it was at the end of December and then try to argue that we needed less stringent restrictions there & then just comes across as sticking your head in the sand. The usual bounceback in cases once lockdown ends that we've seen before will be significantly lessened by the ongoing vaccination program
