If you can provide some evidence that published ideas that have been soundly defeated get resurrected unjustly and that this has harmed progress, then you might have a point. This hasn't happened that I know of.

For instance, the best example I can think of are local, realistic interpretations of quantum mechanics, which most physicists consider to be soundly defeated by this point. However, some of them are completely warranted (like 't Hooft's cellular automata interpretation of QM), and the debate has actually driven some great work in quantum foundations.
