If you were going to wildly exaggerate the size of the Coast Guard force we'd need, why didn't you say millions?
LOL!
Yup. You'd need a friggin' HUGE Coast Guard to effectively patrol the seaboard and the Great Lakes. Most of the patrol boats don't have long-term living quarters aboard, so you'd have to build at least five for each patrol station (and there's a bunch of those). Then you have to add in people to pay those patrol boat crews, feed them, provide base security, and so on, and so on...

Gosh, I guess you don't LIKE being shown reality.
