Once you concede that the government has the right to strip immigrants of their liberty, you've conceded that they have the right to strip everyone of their liberty.
Imagine that you are a currently a citizen of New Hampshire who supports immigration suppression laws.

If the Feds then told former New Hampshirites that, as a non-citizen, you were no longer allowed to live and work in the US, on what grounds would you object?
You think the Feds should be able to strip non-citizens of their right to live and work where they please, right?
If they kidnapped you and dumped you in Cuba or Venezuela, on what grounds would you object?
You believe that the Feds have the right to do that to non-citizens, right?
