Because it has infected tens (probably hundreds) of thousands of people around the world, completely overwhelmed hospital systems, and there's very little reason to expect it will different where you are.
Is it killing a significant amount of non-immunocompromised people? I haven't devoted a lot of attention to COVID-19, but would assume it doesn't have a high casualty rate among healthy people who practice the basics (rest and hydration)?
I guess one way to look at it is that it's a model for handling a much deadlier bug. And the world is doing a mediocre job at it.
As a point of reference, there are typically about 1000 free hospital beds[1] in the state of Kansas, for a population of 2.9M.
