Yeah, no, there were no enforced quarantines in places other than East Asian countries.
An enforced quarantine was what they did in Venice 750 years ago: armed men on the beaches, armed men aboard galleys patrolling the quarantine anchorage, quarantined ship crews on their ships until 40 days without a case of disease aboard ship.
Quarantine is a rather brutal process -- but it's better than losing significant numbers of your population to infectious disease.
(The USA has lost roughly 1/3 of 1% of the population or 1,030,000 to Covid19 in 2 1/2 years. The excess deaths suggest that the actual losses exceed that, but absent actual testing, who can tell.)
