>>registrars between you and the root can spoof you.
Not good.
It would be much better to require two (or more) cert chains at the same time that won't cooperate.
For example, take a cert from USA, North Korea, and India. You could only be spoofed if theese 3 CAs or their intermediary cooperate.

"The two main debris fields are the ring of objects in GEO and the cloud of objects in low Earth orbit (LEO)"

it's not a problem of the same magnitude than LEO, but it will become one once you put up "square kilometers arrays of photocells or mylar reflectors". These things will just disintegrate at the smallest impact, and create a large debris cloud. This is why orbital mylar baloons are obsolete since long.
