I'm just trying to separate "dogs from cats" (if you allow me the analogy) in another random attempt to move the discussion into more productive territories. I wouldn't be doing this if I didn't felt we have advance identifying and understanding each other's concerns better.

To discuss to mouses catches we're missing, I've created the other almost-identically-titled thread: http://lists.linuxfoundation.org/pipermail/bitcoin-dev/2015-August/010188.h= tml The title of this one doesn't contain a "not" like the other one. You missed (imagined?) that little detail. In other words, if you want to contribute to this thread, think about "things that could go wrong if we rise the consensus block size maximum". Judging from your strong conviction about the need of an urgent size rise, probably you have thought hard about this before concluding that there's not risk for your favorite proposed size (2MB, 8MB, 8GB, 20GB?). Note that even if you are certain that those risks aren't a concern at this scale, identifying and somehow estimating or measuring (if that's even possible) the risks will be useful for future increases.
