Re: At least everything is in the same orbit
Up to. Yes. But the distribution of the orbits (and relative speeds) and hence average threat is likely to be significantly different to the situation in e.g. LEO.
Of course, even the average threat might be significant. I personally wouldn't like a bullet hit at 0.4 km/s any more than 4 km/s. (Well I might learn to appreciate the slower speed afterwards depending on where it hit but you know what I mean.)
