I don't agree with the idea that keeping the 1mb limit is conservative. It's actually a highly radical position. The original vision for Bitcoin was that it supports everyone who wants to use it, that's why the very first discussion of it ever was about scalability and Satoshi answered back with calculations based on VISA traffic levels. The only reason the limit is there at all was to avoid anyone mining huge blocks "before the community was ready for it", in his words, so it was only meant to be temporary.

Peter, your usual response to this is that Satoshi made mistakes, etc, that he was wrong and that you know better than him. Which may or may not be true. However, regardless of whether he was wrong or right, that is how the project was envisioned and trying to fundamentally change it now is a controversial position - every bit as radical as wanting to change the inflation formula.

It's actually me that's the conservative one, because I advocate "staying the course".
