I don't think this paper is very good. Because of the huge age and co-morbidity influence in covid mortality, the very large number of excess deaths correspond to a comparatively (eg compared to median death) small number of QUALYs. But as a functioning western society it's a bit unclear how you could action this fact, as "just let the old die" has severe logistical problems ignored by this paper - even if you buy the argument that the cost of the pandemic response exceeds the cost of the pandemic itself in QUALYs, I don't think you could action their advice.
