I am not sure that I agree with that, JC (at least not in general). Look at 
base connection for the Tashjian (old Tri-ex) crankup tower. The base of the
tower is not only electrically connected to the rebar cage, it's actually 
part of it
(each of the 3 flange ears that the tower bolts against are welded to a 
of large diameter rebar which in turn is tied to the rest of the cage.  I 
think the
US tower bases are done more or less the same way.
