Starliner is meant to be reusable, except its components can’t even make it through one run uneventfully [1]. It’s mated to the Atlas V, a buggy, disposable stack that’s already been EOL’d [2].
NASA’s money would be so much better spent—even now!—on literally anything else. The amount of practical redundancy provided by Starliner is zero.
