I admire your ability to see the silver lining. I see it as selfishness to the point of toxicity.
I think the ship has sailed on asking people to wear masks. These people--whether they have a borderline ODD tendency to "question authority" and "stick it to the man" for the sake of "personal freedom" (read: selfish masquerading as principled), or if they just can't care about how their choices affect other people anymore because we are n months into a pandemic with no end in sight--have made their choice.
They are not willing to do the bare minimum such as wear a mask or not attend giant parties. I have to say, as far as measures to slow the spread go, these two requirements are incredibly fucking easy to abide by.
So I say shut the power to their party so it sucks, and make it harder for them to spread the virus even faster. Fines based on a percentage of income would be better.
