its hopeless, you will forever believe 8MB blocks would break bitcoin.
They would. Even a 2 MB block size limit could, but that's what the 'hacky workaround' with those limitations is all about. It is you who does not know things, and it is you who is being fed lies. Do you even know what the difference between linear and quadratic scaling means? Have you even heard of the big O?
The questions are: Is it optimal? Is it necessary? Is it worth risking of contentious hard fork over? The answer is a resounding "No" on all fronts.
I concur.
