PM,
I understand you feel you're making some form of logical argument that Hamilton should have won all of the races this year and he'd be world champion. I could make the same argument about Felipe Nasr or any other driver in the field. "Man, if Jenson Button had simply won 12 races this year he could have been world champion...".
Do you understand that argument is completely irrelevant when we're talking about 30+ points which were lost due to circumstances beyond the driver's control? I'd be making the same argument if Rosberg had blown and engine and was 30 points behind Hamilton (you probably wouldn't, I understand). How can you disregard a large portion of points lost due to a mechanical failure?
It's simple mathematics. If Hamilton loses by 30+/- points it will be a direct penalty from his mechanical issues. If he didn't have an engine blow-out and then lost the world championship by, say, five points - then yes you could go back and nitpick whatever nonsense you feel compelled to. It's simple math buddy.
