This is a good candidate. Although some of this effect might be countered by people dying because they didn't get elective treatment.
Regardless: when you change pretty much every parameter of society (risk behavior, driving, crime, health care, ...) I don't understand how one can use the overall death statistics and try to attribute them to Covid.
I think the elective treatment theory is a better point than my driving guess. If you have a disease and your options are to get surgery or take medicine, you are probably being pushed towards non-surgical options, even if that would have overall worse results on average. This might ultimately raise the mortality rate, but would temporarily depress it.
Anecdotally, I definitely find myself trying to be safer right now. I have avoided ladder work on my house and been super careful when using a knife. I just do not want to go to a hospital right now.
I think looking at the overall death statistics are super interesting though. If traffic deaths fall, that is in some ways a byproduct of Covid. If more cancer patients die, that is also a byproduct. All of this goes into factoring how much damage and protection both the disease and the quarantine orders have caused.
