I largely agree with most everything that you said, regarding enforcement pragmatism and the like.

But I must remind that, at least in this particular conversation, we're talking about people who've just had the illness in question. We don't know how many of the 1,500/day are people who have previously contracted the illness or else contracted the illness from someone else who previously caught the illness, but in all likelihood the proportion of such cases is likely very low. So referencing the 1,500/day likely has very little relevance to a discussion of natural immunity.
