COVID Masks

Why is it so difficult for a person to wear a COVID mask in a closed setting? So-called personal freedom in this context is NOT as important as 1) actually helping to protect oneself from the possible harm cause by a serious disease and 2) protecting the health of family members and other people. People in other cultures have been wearing such masks to help avoid contracting and spreading disease without complaint. (BTW, the cases of cold and flu dropped while masks were required.) This individual freedom thing is so stupid and selfish. Do you actually like the idea of extras millions of people dying and even more millions suffering long-COVID, not to mention that this disease and future such diseases cost and will cost the economy billions in lost revenue and increased prices and taxes. I, for one, do not like the inflation that the disease caused.
