I have a hypothetical question. Let us pretend that a hard fork indeed happened. For this example let us use BitcoinXT as the new version to be used in the fork. If the hard fork ended up like the one that happened to Ethereum, who is to blame and what should be done? Now we have two Bitcoin chains and both have die hard supporters unwilling to let go for each.
If there is anyone to blame it is the proponents of the hard fork, because they initiated a network split. There is nothing to be done about it. Miners will mine any chain which it is rational to mine on; there's no way to stop miners from securing either chain. And whether it's rational for miners depends on users; there is no way to force users to use one client or the other.
So if users remain on the original chain, the network will likely split and we will permanently have multiple incompatible networks/blockchains. It doesn't matter which chain has more work (POW) because the two networks cannot communicate with one another.
There would not have been a need for a split if people weren't so stubborn as to religiously hold on to an obsolete 1MB blocksize limit.
Other than a mindless fearr of a hard fork, give me 1 solid reason based on logic against a block size increase.
