They're not your enemy _now_ and yes they can affect your life. You seem to be thinking about it as if someone in the CCP will wake up one day and decide to do something about "ok_dad". You're not alone in the country, right? There are other people that influence your life. While you may not be directly targeted, you can be indirectly affected by their ability to influence _other people around you_.
And when it comes to data, individual data is not that useful, it's aggregate data that's useful, which is why we _collectively_ have to prevent this from happening. For example, you don't have to give me your phone number, it's sufficient that your friend who called you gives me access to his contact list.

Two things can be bad at the same time. You could be enabling a foreign country to affect your life, and you could be targeted by the US government.
