Okay then, you've laid out three choices - the bad, the worse and the completely unrealistic.
Not as unrealistic as the notion in 1776 that a group American colonies with very little military experience or means could declare independence from the world's largest superpower. Political changes don't have to be gradual.
We have can do this legally. We have the threat of a Constitutional Convention. It's a big club that could be used to roll back a lot of what's been done. But we have to play chicken and we can't flinch. And we have to be prepared to go though with it if they don't back down.
