If this is for an insurance claim, then I doubt many insurance adjusters would distinguish between a damaged bike and damaged components. The fact that the wheels are damaged, the shifter and other parts scratched up, and the shifter twisted on the bar would demonstrate that they should pay you for the value of your bike.
The downside is that most insurance will only pay fair market value and not replacement cost. I would start thinking about how you are going to convince the insurance company of the fair market value.
Once you settle up, you can decide to either buy a replacement or repair this one.
