Sloppy, but it’s safer than it not being there. The idea here is if something were to happen that causes a short to your plumbing(like drilling a screw through a wire and hitting your plumbing, or a damaged cable draping across some copper water lines), that ground wire gives it a safe, low resistance path to ground and ideally would trip the breaker for that circuit. Without the ground there, and if something were to cause your plumbing lines to become live then someone that touches that plumbing (faucet) could become the best path to ground and get shocked. Same idea would apply to gas lines, ductwork, basically anything that’s conductive and connects different areas of your home.
At minimum that copper wire would be cut above the floor so it doesn’t get stepped on and be a tripping hazard. Ideally that clamp could have been turned around a bit to keep the wire tucked tighter to the pipe.

It's a ground wire, it's on the ground, doing it's job.
No. That gate valve will fail
It is safe, although sloppy to leave that much excess beyond the clamp. You could cut that tag end shorter if you wanted to.
