another thing...miners can always sell privately i believe, their electricity bills is far less than their profit

Whoever pushes the fork has a strong incentive to see its side of the fork be recognized as the only "universal" bitcoin, in the end the other side of the fork is doomed and could only serve some anecdotic purpose in the long run at best. Most likely it will just die fast.
isn't this a way to kill adoption instead of increasing it? because some merchants will simply abandon the whole bitcoin idea if they don't like the new fork
