So more people will get ill and die
There is absolutely no evidence of this at all. Ten of thousands of cases for many months now is resulting in a fall in deaths and hospital admissions.
The only effective measure against Covid is vaccination. Everything else is window dressing. Viruses/pandemics follow a pattern. You can "flatten the curve" fine, at the beginning, and most people will go along with that. But when you have an effective prophylactic (vaccine), and now treatments, the evidence for additional measures, whether that be masks, or wfh, or vaccine passports, loose their value, and the public will eventually say enough is enough.
