E.g.: he quotes something like "40% excess deaths due to COVID, as certified by a doctor"
And then claims: "hence the other 60% are not COVID related".
That's not what that means! The other 60% is deaths that are EITHER due to COVID, but not certified by a doctor OR due to other causes, including indirect deaths due to the pandemic.
Regarding certified deaths: Especially later in the pandemic there were lots of people taking the disease less seriously. Testing rates dropped. Fewer people bothered going to hospital. Symptoms were less obvious but still causing deaths. Some guy on a breathing tube dying is obviously due to COVID, but some woman keeling over at home because their heart couldn't take repeated mild infections is not so obvious.
Regarding indirect causes: There were also lots of excess deaths due to elective surgeries being delayed and preventative healthcare being put off. Hospitals were overwhelmed, and many procedures were simply unavailable. These are indirectly caused by COVID, but would not be "certified as COVID-caused by a doctor".
Not to mention suicides due to lockdown isolation, work from home. My neighbour killed himself because he was a very social person stuck at home for a year and a half!
The correlations he lists are also not proper evidence. The healthcare issues due to delayed elective surgeries would accumulate and take 1-2 years to show a noticeable effect, coinciding with the vaccination rollout schedule.
To get a scientifically valid statistical result, you'd have to do some sort of multivariate analysis that doesn't just look at an aggregate graph for an entire nation, but breaks down vaccination rates and excess deaths by smaller regions.
You'd then have to show that increased vaccinations cause increased deaths, independently of other factors such as the time since the pandemic started (and hospitals got backlogged), infection rates, etc...
