Absolutely, and then add on the entire infrastructure demands of rare
earth mining and refining and distribution for, say, twenty years.
Then ramp it down as it's moved offworld, to the point where it's less
than when we started.

Just solar sail the refined minerals back to Earth's gravity well then
aero-brake them (using ablative shields made from refining by-products)
into the ocean for pickup.

Yes it's a bit Lensman. :-)
