If people are "fed up" of lockdown because they can't get a haircut, that is something to be upset about.
The thing is that these lockdowns are far more damaging in other areas. For example, farmers throwing food away because they are simply not allowed to ship it to the next logistics point. Or people in Third World countries forced to stay indoors where they have no supplies. These people aren't "fed up", they are struggling to survive.
EDIT: And I think what many people are really upset about is the lack of transparency in the data. They feel like they are being fed lies. For example. we had a "hot spot" of over 700 cases and they locked down an entire company with thousands of employees. 700 cases, that immediately implies 700 sick people, but the fact is that only a few showed any symptoms, mostly mild symptoms. The same goes for all the Corona-deaths that were falsely attributed to Corona despite negative tests because the patient exhibited Corona symptoms while dying. As Elon Musk asked, how do you die in general without coughing or shortness of breath? And it is things like this that are getting people, including me, to start being "fed up".
Honesty, something I don't expect from this system, from politicians, from scientists, from corporations and from media, honesty is the best policy.
