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.
You continue to repeat this -- but it is only half the story.
Satoshi also intended the subsidy-free, fee-only future to support bitcoin. He did not describe fancy assurance contracts and infinite block sizes; he cleared indicated that fees would be driven in part by competition for space in the next block.
Unlimited block sizes are also a radical position quite outside whatever was envisioned by the system's creator -- who cleared did think that far ahead.
