Because this rationale completely ignores the fact that attendees who acquire it at the gathering will spread it to others who did not attend this gathering.
How will that happen if everyone else is social distancing and taking other precautions?
You are responsible for your own safety ONLY.
.
That's ridiculous. The morons who are insisting on their "freedom" are doing so out of hatred for their neighbors. They need to start showing some patriotism and respect for others. There is no such thing as being responsible only for your own safety. The entire field of tort law is based on the concept that the risk posed to others was foreseeable.
BTW: the other day when I was shopping and picking up something in the refrigerated section (which has glass doors) a white male approximately 45-55 walked straight up to me and reached around me, forcing me to step aside six feet, and then proceeded to do a ten-minute inspection of every package; no mask, no gloves, handled many items before finally picking one, this me standing there all the while. He forced me back. There should be a way to punish this sort of scum.
Incidentally, I identified this perp by race, sex, and approximate age due to the current idiotic practice on this board of identifying wrongdoers according to these characteristics so that the misconduct can be properly "credited" to the correct demographic group(s).
