I agree with you on this point. I think the point that I was trying to make is that I would be more sympathetic to the idea of using such a fork as a means of buying time (which it clearly isn't) in order to make changes and then vote on them, but even then, like you mention, the "community" can just fork the code and start a new blockchain. It would be a much more principled move given all the stake they would be giving up, but it would clearly emphasize the point that the witnesses have been claiming to make the past two weeks or so.
