Oh - and...
Our government has broad power to order and enforce quarantines. The federal government, acting through the Department of Health and Human Services (HHS), has authority to order quarantines as necessary "to prevent the introduction, transmission, or spread of communicable diseases." Using this quarantine power, HHS can order isolation of specific individuals, or can impose large-scale quarantines. The latter happens very rarely; the last mass-scale federal quarantine happened over a century ago, during the influenza pandemic of 1918-1919. All 50 states also have laws enabling governors or other officials to order quarantines.
I'll certainly read any facts you have rebutting this - thanks in advance.
