Why do you think that they are wrong? What is your proposal?
They're wrong in so far as they both propose that one particular subset of the system has ultimate control over it (miners in the case of the first post and users in the case of the second). They all have varying degrees of
influence; none has unilateral control. (Also "miners" and "users" are not really decision making entities which is another problem with both arguments -- fallacy of composition/division.)
As far as my proposal, it doesn't really matter because they won't listen to me but I favor a hard fork to 2 MB followed by a
slow automatic increase of maybe 10% per year for say 10-20 years. Slow enough that if it looks to be running out beyond hardware improvements it can be rolled back with 1-2 year lead time for another fork. Ultimately, though, it is up to the various interest groups to work it out or fight it out, because it won't work unless all are somehow on board. Messy and ugly but it is delusional and wishful thinking to think you can remove politics from this process.
