Well, all the antibody studies around the globe have several things in common: * relatively small numbers of participants (< 5000 and therefore only dozens of partifipants with postive results) * focusing on relatively small geographical areas * working with antibody test with a high uncertainty regarding the specifity One argument that strongly contradicts the narrative that a huge number of people already are/were SARS-COV-2-positive is the of positive PCR tests in Germany. Germany performs hundreds of thousands of PCR tests per week but still mainly tests people with some symptoms. If SARS-COV-2 were that prevalent, you would expect a large proportion of the tested to be positive but its only 4% by late March [1]. Every expert I heard admits that there is a significant number of undiagnosed cases. But 30x-60x seems to be quite unrealistic if even only 4% of people with symptoms are positive.
