Just because YOU haven't felt harmed or threatened doesn't mean that others feel that way. I generally agree with you but with some caveats. For example, users should have the ability to opt-in/out of data collection. Additionally there are some actors I would choose NOT to share this data with. Google is one of them.
There's a difference between actually harm and perceived harm. Lots of people feel harmed and threatened by vaccines. I'm not saying you shouldn't have privacy but I claiming you "feel harmed and threatened" isn't really an answer to "what's the harm"
