I think that's rather harsh. People are processing Bitcoin problems (scalability, block size, etc.) in different parts, from different aspects, and with differing information. I don't think calling anything obvious is fair.
I didn't necessarily mean it should have been obvious to you, but it should be for the person you were quoting, especially since it's been brought up many times in the past.
Yes, that's what I meant. I've always believed the time between blocks factor was the thing giving miners incentive to broadcast hurriedly, but I don't recall reading that in any block size debate thread. That's what I mean about people processing problems from different aspects and with different information sets. How do you know most everyone has seen that point mentioned?
