Comparing to influenza helps maintain perspective on COVID-19, indeed.

However, the crucial difference is that influenza has an established vaccine regime.

So people who are more vulnerable to infections of this kind typically are inoculated.
(This also modulates the death rate: since risk populations have higher inoculation rates, they get sick at a lower rate, so the overall case fatality rate is lower.)
There is also the psychological aspect that “one can do something about” the influenza threat.  And we have a lot of data about how this works out.

Now, all considerations of COVID-19 must focus on limiting the spread, until a vaccine regime can be established.  So interventions that would not make sense on an individual basis (e.g., during a period where the risk is really low) still may be justified from a containment point of view.  This includes interventions that, literally, are worse than the disease for the victim.  That, together with lots of unknowns, creates the scary part.
