"It can we can I can." Satoshis intention was to never change the blocksize limit.
Satoshi's intentions really don't matter. He's not here, and this is no longer his project.
That being said, if you care about Satoshi's intentions then it is incorrect to say that his intention was to
never change the blocksize limit.
He, himself, specifically stated otherwise:
We can phase in a change later if we get closer to needing it.
It can be phased in, like:
if (blocknumber > 115000)
maxblocksize = largerlimit
It can start being in versions way ahead, so by the time it reaches that block number and goes into effect, the older versions that don't have it are already obsolete.
When we're near the cutoff block number, I can put an alert to old versions to make sure they know they have to upgrade.
