I find it exhausting that people such as yourself seem to latch onto missed time frames as a reason to just assume all public health policy is bullshit. Yes, because when I say I'm going to finish some software project in 2 weeks, I absolutely always get it done in 2 weeks.
These are estimates. They are sometimes (often!) wrong. Sometimes they're wrong because the problem was underestimated. Sometimes they are wrong for political reasons.
Yes, "flattening the curve" took more than 2 weeks. Big deal. Doing so did absolutely reduce pressure on ICUs and saved many lives. And hell, if everyone had actually followed all the mandates and guidelines at the time, maybe it would have only taken two weeks. But people don't, and it's always hard to gauge how many people will refuse to cooperate, and in what ways, and exactly what effect that will have.
The reason the goalposts are moving is because this isn't a well-defined game with strictly-set rules. The virus doesn't care about our rules or projections. If it mutates, and the new variant does better against our vaccines, then... yes, the goalposts will move. Our utter failure to get high vaccination rates in poorer countries is likely a big cause of the new variants. It's all well and good to be sitting in a highly-vaccinated city in the first world, but all it takes is one person to fly in from somewhere with a new variant, and you're hosed.
You miss a time frame if you say "2 weeks" and end up having to lockdown for 3 instead. If you say "2 weeks" and end up with lockdowns for years you are either incompetent or lying or both.
