what's to stop a thief from just unbolting it?

Nothing is ever completely theft-proof. If a thief really wants something, they will get it. However, anything you can do to make this as noisy and time-consuming as possible helps deter would-be thieves from even bothering because there are likely much easier targets in your area. To get to the bolts, they'd have to contend with removing the cover, removing the hammered-on caps and ball bearings under those, and then unbolting the screws. It would take them a lot of effort and a really long time, and they'd likely make a lot of noise doing it. Unless you've got something really valuable and you don't have any neighbors, I don't see any thieves bothering with this stuff. This is about as safe as you can get your bike chain anchors.

How difficult is it to remove in order to change location? (example, moving to a new place)

I think if you pound the metal bolt covers in to place after installation via directions that removal might be challenging. I have not moved mine after it was installed, this is merely speculation.

how much damage is caused from installing this device?

I embedded it into freshly laid concrete with the provided bolts. I didn't have to drill the holes, but it hasn't caused any damage the way I installed it. Hope that helped, sorry!

Is the ring one continuous piece of metal, or is it sort-of a C shape, with the ends of the C being hidden in the base?

It is definitely ring-like, but I think the base part was welded to the C part.
