Well, I indeed do not believe that patents are actually good, but there's far more merit to the unconvincing arguments that patents can be good than to any arguments that software patents can be good. There are good reasons that many people (particularly among those who understand software) fundamentally oppose the entire concept of software patents without opposing all patents.
It's rather disingenuous, the assumption with the structure of your question is "within the framework of 'patents can be good'".
