You have raised the biggest objection to Cali’s secession. We can not allow it to become a staging area for hostiles.
My predictions if Cal-exit happens. The delta smelt will start to come in cans like sardines. Desalination plants will crop up all along the pacific coast. Same with oil rigs. Prisons will be emptied as all illegals are held at empty bases until sent back to their home countries.
Finally, within a year, every liberal politician will be taken out and hanged after most California citizens realized they were the cause of the devastation.
It would be wrong of us to try to insist that those who want to exit must stay, just as it is wrong for people who are seriously out of step with (and ignorant of) the rest of the country to insist that everyone else must abide by their extremely Byzantine rules and social codes.
But the land is ours. Ownership derives from permission granted by the United States of America. This can be withdrawn. What do you think the basis for eminent domain is?
It already is a staging area for hostiles.
