I don’t know if this is worth it, but since you’re into numbers and statistics...
A. Seems like we can agree the flu is bad. It costs billions of dollars per year and as you’ve pointed out, a lot of people die
B. There are some varying estimates depending on situation, but from current evidence, let’s assume coronavirus death rate is at least equal to the flu.
C. R0 for the flu is about 1.3. Current R0 estimates for coronavirus are around 2-2.3, so significantly more transmissible
D. There is a vaccine for the flu and even with a vaccine CDC says around 8% of the population still gets it each year. The flu has a predictable seasonal cycle.
So, probably higher fatality rate, higher transmission rate, no vaccine, and we have no idea how it is going to change seasonally. Seems like probably worth making efforts to minimize impact. Will some people overreact? Would a lot of other diseases spreading at this rate be a hell of a lot worse? Sure, but seems kinda dumb to laugh off global pandemic just because you don’t like some people or outlets that are saying it’s serious.
