It's interesting that you don't mention one of the conclusions of the study: getting a shot after having recovered from COVID gives you the best immunity, and that is confirmed by all the studies, with all measures of immunity. And that's even more true with Delta variant.
Oh, and your conclusion: "more harm than good" is obviously false. I'm glad you recovered well, but many didn't. Without even talking about the deaths, just the number of people with long-haul makes your statement wrong.
