> having antibodies doesn't mean anything

Not sure how to address this, of course it means a great deal. As a proxy for exposure and coupled with studies that show impact of known exposure towards immunity, its great evidence. Whether someone was harmed by their infection is a moot point for those who've gone through it.

In a place like Australia with only a small fraction of the population having exposure its no wonder the statistics of their hospitalizations look as they do. In my own state hospitalizations have started decouple from vaccine status due to the high degree of natural immunity and that was before Omicron.

If the delta of whatever you are measuring is 90%+ dependent on a single age group then perhaps the guidance should reflect that. Frankly you aren't attempting to honestly address my points.
