You might be misunderstanding the point. Many people have chosen to promote the lie that the vast majority of COVID deaths can be dismissed using this reasoning, rather than a tiny, tiny, tiny fraction.

They ignore the overwhelming "excess deaths" number and pretend that unless a person had COVID and COVID alone listed, with no co-morbidity, it doesn't count, and therefore 99+% of COVID deaths aren't COVID at all.

This is, of course, not true, as the excess deaths numbers clearly demonstrate. If anything, we're under-counting COVID.
