There is a lot of opinions now, and you seem to be conflating a lot of groups of people ad-hoc just as they are of you. It is true that you can re-catch Covid, so the people claiming Natural immunity as some cure-all for the situation are wrong. What if we didn't lock down, and let it spread naturally, then the entire population like your brother would be sick at the same time, thus overwhelming the system and more people dying.
