Perpetual mask laws aren’t quarantines, though. Quarantines are limited-time emergency things. Consider how Poland's Supreme Court, for example, recently found that the government had no right to close businesses or require masks without declaring a state of emergency (which is necessarily a short-term thing). In the USA, with its even more litigious culture and judges favouring limited state intervention, I would expect long-term public-health laws to face even more legal opposition.
