It would be helpful to explain how the "freedom & the Constitution, motherfucker" argument works when talking to Typhoid Mary, the food worker with typhus who kept changing her name to get work as a cook.
"From 1900 to 1907, Mallon worked as a cook in the New York City area for eight families, seven of which contracted typhoid. In 1900, she worked in Mamaroneck, New York, where within two weeks of her employment, residents developed typhoid fever. In 1901, she moved to Manhattan, where members of the family for whom she worked developed fevers and diarrhea, and the laundress died. Mallon then went to work for a lawyer and left after seven of the eight people in that household became ill.
In June 1904, she was hired by a prosperous lawyer, Henry Gilsey. Within a week, the laundress was infected with typhoid, and soon four of the seven servants were ill. No members of Gilsey's family were infected, because they resided separately, and the servants lived in their own house. The investigator Dr. R. L. Wilson concluded that the laundress had caused the outbreak, but he failed to prove it. Immediately after the outbreak began, Mallon left and moved to Tuxedo Park, where she was hired by George Kessler. Two weeks later, the laundress in his household was infected and taken to St. Joseph's Regional Medical Center, where her case of typhoid was the first in a long time.
In August 1906, Mallon took a position in Oyster Bay on Long Island with the family of a wealthy New York banker, Charles Henry Warren. Mallon went along with the Warrens when they rented a house in Oyster Bay for the summer of 1906. From August 27 to September 3, six of the 11 people in the family came down with typhoid fever."

Masks aren't about you, they're about protecting others from you, in a time when we don't have universal testing, and many infected people show no symptoms but are capable of infecting others, who may die. Mary Mallon's spewing of typhus was only stopped when the authorities grabbed her and quarantined her, because she (like many today) was utterly unwilling to inconvenience herself just to avoid killing others.
I'm not saying that shutting down the economy is a good idea. I'm saying that wearing masks to keep your infected snot away from others is a good idea. And "liberty" doesn't mean that YOU get to do whatever you want while all those around you have to suck it up.
