This is why I think hospitalisations are a better measure. Cases by themselves don't tell us very much, especially as we saw with Omicron. If we know that our hospitals are being swamped and unable to cope, restrictions are a good idea to avoid hospitals collapsing.
But in a situation where you have many cases and very few hospitalisations? Restrictions are completely pointless.
The point still stands that any restrictions disrupt the endemic equilibrium and cause an increase in cases and hospitalisations when the restrictions end, which if you impose restrictions every time hospitalisations increase just leads to an infinite loop. Basically you have set the criteria to move round another iteration of the loop, but no criteria to finally get out of that loop.
