> 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.
