Just as a simple example, how do you enforce home quarantine? In Hong Kong, they use a bluetooth bracelet, in Taiwan, they're using a combo of a cell phone tower gate + requiring you to answer the phone and police checking on you if you don't. In China, they have a hardware door sensor that will alert authorities if it's opened. In South Korea, I think they're also using cell phone tower gates. Each approach has different pros & cons when it comes to privacy and effectiveness. Which one specifically do people think is acceptable and unacceptable?
