Do you really think NASA would be fine with canceling the SLS so they can restart a new reusable launch system, or contract with BO/SpaceX for one? Any launch

Do you really think NASA would be fine with canceling the SLS so they can restart a new reusable launch system, or contract with BO/SpaceX for one? Any launch system that's in current development that isn't reusable is obsolete. The likely cost savings are so substantial they make disposables entirely uncompetitive. ULA knows this, Arianespace knows it, and NASA knows it but practices denial because their political support is predicated on a project spending lots of money in a huge number of vongressional districts.
