Yeah... definitely not seeing the logic. I mean, sure those are arguments he could try and make, but I don't think it'll be successful.
Only point I'll address is the one on science. Science is definitely not all fact, and does definitely change. But one data point does not change it. Trump surviving or dying makes no real impact as he's just one of 7,000,000 and has far better access to medical treatment than virtually any other person. The more important point is his utter lack of care and his inability to even protect himself with the tremendous resources at his disposal.
It really doesn't change the science, I agree, but people typically aren't the most science oriented. There's many ways to sway people, especially when it comes to power and influence. This is especially clear from what's thought by the left, which seems weird, since they're supposed to be the one's who believe more strongly in science.
If Trump recovers easily, he's likely to try and use that as justification for not being more cautious and how he handled things in the past. For all we know it was someone else who broke protocol and gave it to him. If it puts him down hard, he's going to have a hard time explaining it all away.
