"To reduce humanity’s environmental footprint toward a sustainable
level, it is necessary to reach consensus on footprint caps at
different scales, from global to national or river-basin scale.
Footprint caps need to be related to both production and consumption
(32, 55).

"The various components of the environmental footprint of humanity
must be reduced to remain within planetary boundaries."

Why?

There is already a $100 billion dollar satellite communication
business where the expensive parts are well outside the "planetary
boundaries."

Can anyone think of a reason we should not move primary energy
production out there too?

Dr. Peter Vajk discussed this in a book decades ago.
