I can explain it: It is not "giving up" to leave a physical location that is uninhabitable.

When you can't freely transfer money or have private electronic conversations (telephone, SMS, email, whatever) as a median citizen not under suspicion of a crime, you must leave the place in which you are, just as you would have to leave your private home if it were completely flooded or exposed to the elements.

Sure it does. OWS was everyday people visibly and peacefully saying that they are unhappy with the way life is treating them. They were then treated as terrorists by the FBI. This sends the signal that unless you are willing to be treated as an enemy of the state, don't complain. Saying this is "uninhabitable" for normal, happy, productive people is not a widely held opinion, but it is rational.
