Inductively coupled charging stations could bury the copper cables where they were harder to dig out, and it's not hard to embed a sense wire loop in the cable assembly that can generate an alarm as soon as the cable is cut.

This just a reflection of poor engineering design, but neither Cursitor Doom nor ZeroHedge have that kind of insight.

 And how big and heavy does the coil on the car have to be for fast charging?

As far as I know it is only used for electric buses at moment, and doesn't seem to big or heavy enough to attract attention.
Magnalev trains need to shift a lot more power through the inductive link, and it doesn't seem to make them impractical
Since a car typically spends spends 95% of its time parked, charging doesn't necessarily have to be all that fast.
Aluminium coils do tend to be bulkier than copper coils, but they are quite a bit lighter and cheaper.
If you had any grasp of engineering design I wouldn't have needed to spell this out for you.
