> To the extent mandatory quarantines are justifiable

Mandatory quarantines are justifiable, buth their enforcement using surveillance technology is not. In free countries we trust citizens to uphold laws and only punish those who trespass them, not monitor everyone to ensure compliance. We do not have mandatory backdoors in our computers to monitor copyright enforcement, and we do not have mandatory government cameras at home to prevent domestic violence.

> I don't see why it's worse than ankle bracelets.

Ankle bracelets do not require interaction with wearer, while this monitoring is using incoming calls several times a day to ensure you have phone with you. If i were ill with covid-19 last thing i wanted is to be repeatedly woken up by phone calls.

Mandatory quarantines of those with a positive test result seems perfectly reasonable. Mandatory quarantines and/or continuous location monitoring of what should be free citizens does not strike me as in any way reasonable.

Mandatory quarantine is only required after initial entry to Taiwan. After 14 days the person is free to move about without any continuous location monitoring. This is needed because of the presymptomatic period of COVID-19. By cutting off potential vectors of née infections the entire country is able to enjoy normal lives instead of prolonged quarantine. The mandatory quarantine period is also publicized, so the visitors can make a decide if it is worth it to enter the country. Many people have went to Taiwan despite the mandatory quarantine—they are choosing 2 weeks of lockdown then normal life rather than seemingly unending lockdown amid worsening pandemic.
