If miners stop playing stupid games and really want the best for bitcoin, they would stop stomping on the hardfork drums of war, and they would activate BIP141 as they have been told by everyone worth listening to in the space. But what happens when you give stupid janitors the ability to vote on engineering matters? that they will don't do the right thing.
Enable segwit with no stupid hardfork drama, and see bitcoin skyrocket.
Break bitcoin in half, see the price crash, and see everyone involved in the forked chain going bankrupt, with the price going to 0 on Forkcoin, and with Bitcoin crashing but going back 3 years in price and taking another 3 years to recover.
Your choice.
How sure are you that it will reach $10,000 overnight? What if it does crash more if it was implemented because there would be fears of the unknown again. Yeah segwit is good, but not everybody understands it even if they are even holding a significant amount of bitcoins. Any forks doesn't really guarantee that it would skyrocket to be honest.
