I'm sure you are exaggerating somewhat. Like, you probably wouldn't permanently give up your freedom of movement or the vote to stave off your parents' deaths two days or whatever. There are tradeoffs to be made here, and a temporary reduction in privacy might be worth it for the lives that could be saved. I personally think so. Probably most of the population agrees. The people on this site skew privacy-oriented, so you'll probably get less agreement here than in the population writ large.
