This argument is a little bit silly.

There is no such thing as gravitational shielding, so arguing about the
effects of it is meaningless.

You may as well argue how many pixies you would need to turn a turbine in
a power station, as you are just as able to use pixie power as 
gravitational shielding.

There are too many real and valid problems in physics for physicists to
waste their time thinking ideas out of star trek. I suggest that you leave
the science fiction to the writers, and look at something a little more
pertinent to today's problems.
