I agree totally. I haven't seemed much informed discussion along these lines, but the only two possabilities I see are: 1) The antibody studies are incorrect, and over-counting the infection rate. 2) COVID-19 spreads much more easily than influenza, and so a large percentage of the population has become infected much quicker than typical influenza spread patterns. Neither option is great, though to me of the two, #2 seems more hopeful, since assumedly we'd get herd immunity relatively quickly.
