No, I think 1 MB is just as arbitrary as any other size proposed.

No, if the changed rule only serves to limit centralization, then how that limitation to centralization is affected should be the first thing to consider. If miners' concern was only the amount of profit they make they wouldn't mine free transactions already. You cannot possibly know what all users' are concern about, so I will just ignore any further claim in that direction. Talk for yourself: your arguments won't be more reasonable just because you claim that all users think like you do. >> Also I don't think "hitting the limit" must be necessarily harmful and >> if it is, I don't understand why hitting it at 1MB will be more >> harmful than hitting it at 2MB, 8MB or 8GB. > > > The limit won't even get to be hit, because all the users that get thrown > out of Bitcoin will have moved over to a system supporting a larger block > size.

Nobody can't control the implementation that I (or other people concerned with centralization) run either. >> How is what the the majority has been told it's best an objective >> argument? > > > Don't fight the market. The way the system is designed, the miners will > follow along with what the economic majority have decided. How is allowing fees from rising above zero "fighting the market"? The system is currently designed with a 1 MB limit. I don't think that's sacred or anything, but I really don't feel like I'm fighting "the market" or "the way the system is designed". In any case, what do "the market" and "the way the system is designed" have to do with what the majority have been told it's best (which you seem to think should be a source of truth for some reason I'm still missing)? >> So if you say 8, I must ask, why not 9? >> Why 9 MB is not safe for mining centralization but 8 MB is? > > > 8MB has simply been the focal point for this debate. 9MB is also safe if = 8MB > is, but I suppose the opponents will be even less happy with 9 than with = 8, > and we don't want to unnecessarily increase the conflict. Why 9 MB is safe but 10 MB isn't? The "conflict" won't be resolved by evading hard questions... >> It seems like the rationale it's always "the bigger the better" and >> the only limitation is what a few people concerned with mining >> centralization (while they still have time to discuss this) are >> willing to accept.

Will there ever be a debate that results in "further blocksize increases at this point are very risky for mining centralization"? How will we tell then? Can't we use the same criteria now?
