I love it in principle!
I've already decided to role-play "anti-greenhouse gas" a sunshade thats installed by terraformers, because other than stratospheric sulfur and nitrogen rich clouds lowering albedo, theres not really a such thing as "anti-greenhouse gas," at least that i'm aware of.
Achieving orbit is functionally instant already, so I conclude that civilian spaceports have space elevators to assist in loading equipment.
As for chunk moving, I think thats great too, but it might be a tad too easy to fortify jump points, which is probably why we can't move them as is. I'd tow rings of them around jump earth's jump points and install plasma carronade PDCs and swarms of missle launchers. In aurora 2, if steve gets rid of (or gives alternatives to) jump point travel, we'll probably be able to tow them all over as a function of object mass.
