Power driver for copper grounding rod.

That could defeat the purpose of the ground rod. In theory, it needs to be completely in contact with the surrounding soil, in order to bleed off electricity into the earth.Even if the pipe is removed, there could be voids left around the ground rod.

You did not understand how the process of using the sacrificial pipe would be incorporated
you do not drive the pipe in the ground along with the rod you cut off sections of it as the hammer drives the rod through it the pipe is only there to assist in keeping the rod from bending like a loose sleeve or guide and may or may not be needed with the electric hammer
