Even with no connection, if the tower is close to the house everything
inside will be vulnerable due high voltages induced into electrical system
from a lightning strike.

At the risk of starting a flame war (wouldn't be the first time), I
have to question the purpose of running a ground wire from the tower
to the shack.
What is it you are trying to accomplish? Or putting it another way,
what current are you expecting to flow between your tower and your
shack?
If your tower takes a direct lightning strike, won't a small
percentage of the strike find its way into this ground wire, and since
the wire to earth connection is not zero ohms, some of the strike will
find its way into your shack?
Even if you disconnect your coax and rotator cables during a storm,
this ground wire leaves your shack vulnerable, doesn't it?
Does not sound good to me but if there is a good reason, I want to
hear it.
