Not everyone can just leave. For example in my state if you have joint custody you can't leave the state with your kids without your ex's written permission.

are you gonna pay for their plane/bus/train ticket? you gonna sign their kids up for school?

Yeah, while a gun might protect you from a violent individual in the right circumstances, it does nothing to actually protect your rights beyond that.

A gun can't get you medication if a doctor is forbid by law to treat you, a gun doesn't allow you to cast a vote and have it counted, a gun can't stop them classifying you as a sexual predator etc.

Guns are actually mostly useless, even at keeping you truly safe.
