Not all mobility drives up cases. More people are going out now. But, if they go out to the local rose garden, it doesn’t drive up cases. It is mobility to indoor locations that matters.It’s not npi but mobility. You see the same tail in Sweden and Florida for instance.
but in any case this is also where you divorce from reality into math world. If caseskeep slowing they must eventually approach but not reach zero til you get down to one patient or so per week. This runs contrary to the notion that it’s endemic. Reason? You can’t lock up the population in perpetuity and as long as people are circulating and the thing is endemic (meaning there is no herd immunity even at 95% because the thing is constantly mutating) you are always going to see that effect regardless of npis.
At that point, you’re just playing with semantics. Call it NPI for closing/avoiding the indoor location. Or call it mobility, for going to the indoor location. It’s the same thing.
I do not find the hand-waving assertions about “endemic” to be convincing. There is a lot of ground between 750 deaths per day and “not quite eradicated”. You are using the word “endemic” to make the two sound equal, despite the fact that they are not.
