So you want a hard fork to destroy bitcoin and it's dominance, and the other arguments you made were just nonsense?
STAHP. Educate yourself. Don't you know that bitcoin has already hard forked several times in its history?
https://github.com/bitcoin/bips/blob/master/bip-0050.mediawikiBitcoin didn't split in half - there is still only one bitcoin. When it becomes absolutely necessary to modify the protocol, sane people work together and get it done. Like when the blocks are totally full, and people have been waiting for years to do a trivial blocksize increase...
Even if bitcoin DID split into two chains, one would have more hashpower, and would therefore be more valuable than the other, like Ethereum did. Ehrmagerd, it didn't die!
Bitcoin dominance is ending because the blocksize is still too small.
