It's wild, I have worked internationally for a long-time and the rule when going to certain countries was bring a burner device. Going to China essentially meant the device was nuked on return to the States, now it is the same feeling to/from the US.
Protections at the U.S. border and within the U.S. are actually pretty good. Much of Europe isn't as good. Hell, the British will throw you in jail for refusing to unlock.
