Well you can talk about how it negatively affects the budget all you want, but the fact is they already DID create damaged CGI models. Those models don't magically disappear and have to be recreated after every use. They still exist, and they can be easily re-animated. It's not like physical models that need to be strung up and filmed with a specifically mounted camera on tracks for every animation. They could have taken those CGI models and flown them around however they wanted.
Regarding the rest of your post... My God, I think you've finally gone off the deep end.
