Earlier quoted context omitted.
Given the choice, I think most people would choose the app option and to isolate in the comfort of their own home.
That is a false choice / false dilemma. "Which poison would you rather take" is not a meaningful choice. And what comfort? Facial recognition in your home? GPS tracking? RANDOM pings that send police officers to your house for an in-person quarantine check fi you don't respond within 15 minutes? Stop pretending to think about what most people would choose, and wake up to the reality staring you in the face.
Having an app on your phone that lets authorities check if you're self-isolating sounds totally reasonable to me. When you've finished your two weeks isolation, you just uninstall the app and move on with your life. No big deal.
