So the question isn't whether we should or shouldn't change a block size. It's how the hell do we change the block size? Can you change the blocksize? Please enlighten me on how you intend to change the blocksize in everyone else's client? Bitcoin has become too large for even developers of the primary client to forcefully change, and they're certainly not going to risk their own reputation by attempting to change it against the will of users.
So how do you even get the consensus of users of the system to agree to whatever blocksize increase you intend to have? Attempts at civil discussion were shut on both sides. There were some not willing to compromise on the existing blocksize, or even asking for smaller sizes, while others were not willing to accept anything but complete removal of the limit. The correct action was taken to do nothing, since it was too controversial to force one opinion on everyone, and would've set a terrible precedent that a few developers have the authority to specify the rules on behalf of everyone.
Bitcoiners have settled on the fact that nobody is in charge. Bitcoin Cashers are still arguing about who's going to be in power.
