I agree with you, sometimes he doesn't accept a situation is fairly futile e.g. Valencia this year. 100% Maldonado's fault but the overtake was going to happen anyway so he should have yielded.
Today I feel enough room was given and very few on the grid would have pulled completely back. Hulkenberg made an unusual error (not many cars were spinning at turn 1).
Well it is what it is. I feel sorry for Hamilton that his last race with Mclaren didn't end on a better note and look forwards to seeing what he can do with that Mercedes. A lot, I reckon. Rosberg is a fast qualifier, but I think he's no Button over a season of racing.
I think the bottom line is that in every year Hamilton has had more crashes, more contact, more strategic failings and more mechanical issues than Button. It is what it is. He still beat Button 2-1, Button scored more points overall. It shows that aggression and speed can beat calmness and craft, but possibly not overall. They still have 1 title each after 3 seasons together, which is I feel an under-achievement for both of them, despite me also believe they have been an awesome driver pairing. Go figure!
That first season was key for me, that fact that Button was so close to Hamilton despite being new to the team is I think underrated. Very few drivers join a team, especially were the incumbent teammate is a world champion and has a reputation for being the fastest guy in f1 and put up a strong challenge. The next 2 seasons were blighted by Hamiltons head and then Buttons set up....
Like someone else said, I'm pretty comfortable with my own conclusions, for me the reason why they are close is obvious.
