Yet you're advocating to arrange things for
everyone according to
your principles which can also, demonstrably, cost lives. I'm advocating that individuals make choices for themselves about when to work together to solve a crisis, or when to avoid one another, or when to collaborate with their government, or when to oppose it.
Totalitarian regimes start with the people being stripped of their freedoms. In every case throughout history, they have stripped people of their rights to speech and defense.

Then advocate for a better healthcare system and government accountability. They don't need to have the system to track people in order to provide healthcare, restrict foreign travel, or issue public guidance on how to handle the situation.
Besides, most people would happily volunteer the information, assuming it was on their terms and reasonably secure. But it never is.

I agree, it should be. But you're not counting the lives lost or destroyed by the choice you favor. The "compromise" isn't to give up rights, it's to improve healthcare and preparation for situations like this.
Evil regimes killed 100+ Million people in around a 100 year period. Not allowing governments the power to do that level of evil saves more lives than the coronavirus could ever take.
