Again, your argumentation is problematic and therefore hard to argue with.
Your first point depicts a fictional anecdote that tries to prove that terminally-ill patients with a positive COVID-19 test could have lived longer. It's like saying "If someone has stage IV cancer and tests positive for COVID-19, that does not mean he died due to COVID-19. Heck, he could have even died due to multidrug-resistant bacteria"
What's your source? What's mine? What does it add to the discussion to bring up fictional scenarios?
Regarding your second point: Source? How closely does excess mortality correlate with COVID-19? Could there be other causes? We are talking about highly complex situations that need to be thoroughly analyzed.
