'Burner' phones might be made illegal

Great idea on paper, will not work in real life. You take the store bought phones out, you still have a solid market of phones being sold online. They are often unlocked, and able to be used anywhere to include the prepaid phones.

Hmm. . . . Road Warriors, VPNs, other small personal devices, calling apps. . .

There are other ways to go around this. Will not work.
