What we're trying to tell you, Xan, is that things just aren't that simple. Here's the message coming from On High, from what I suppose most people here would consider a "trusted news source":

"The nation's preeminent infectious disease expert says he believes the country can expect "some degree of normality that is close to where we were" by the end of next year if 75-80% of the population is vaccinated."
And since December 9, Fauci has revised that estimate of the % of population who needs to take the vaccine up to 85-90%.
You're right that the lockdowns are in effect because most people believe those measures to be necessary. Why do they believe that? Because that's what the media and the government are telling them. Well then, they won't change their minds until the government tells them the measures are no longer needed. It's not at all clear to me what conditions will have to exist before the government will send that message, and whether those conditions are at all realistic.
