The leap to "we need Sam Altman's Worldcoin to track everyone" as a solution seems like an extreme jump that skips many less privacy invasion, less expensive, less insane solutions.
In-person verification is something they should go back to. I did most of my classes online when I was in community college but I had to go to the registrar to meet with a counselor and the bursar on campus to finish my admission. After that I never went to campus again. I think that is fair.
