They have three options. One, they can choose to live and operate under those rules. Two, they can work within the system to change the rules. Or three, they can go somewhere that has rules more to their liking. This isn't a prison; they can leave any time they choose. One could even argue that by staying in the country, they are (informally, implicitly) consenting to be governed by its rules.
But instead, they try a fourth alternative: Stay, but pretend that the rules don't apply to them because of laughably bogus legal theories. That doesn't work, no matter how many new legal theories they try, and no matter how much bogus logic and philosophizing they throw at it.
We've got a lot of non-sov-cit people who don't consent to the rules. We call them "criminals".
