Does the current in the earth from the ground connection move as a conduction current . . . ?

Yes, true conduction current flows outward through the earth from a Tesla coil transmitter's ground terminal. Assuming a uniform texture and composition of the surrounding terrain, this current diminishes in strength equally in all horizontal directions as the distance from the terminal increases. This situation changes if an identically tuned Tesla receiving transformer is brought into operation at another location. In this case there is an increase in the current that flows from the transmitter's ground terminal and a conduction current passes through Earth in direction of the receiver's ground terminal.

This looks quite excessive. There is no way where the transmitter can be aware of the existence of the receiver, if it is out of its local field. The receiver receives signal significant time after it was transmitted, and can't inform the transmitter to redirect its ground current on its direction. The power transmitted by radio stations does not depend on the number of receivers receiving the station... The energy that is not recovered by the receivers, taken only from the electromagnetic waves at their immediate vicinity (their local field area), is lost.
