Nah. If piracy didn't happen then why would the companies put in the extra effort to protect their stuff?
Because they're creating data, not carving a masterpiece out of stone. You can easily replicate data. DRM is more about preventing 3rd party sales and transactions, which many gamers believe should be a right, than it is about stopping pirates. You have the right to re-sell damn near anything you own....but not software, oh no. Because it exists in that magical place of non-physical reality where special rules apply.
Pirates just make a much better target than well-meaning users, who the DRM is truly targeted at. You can get well-meaning users on the side of DRM, even as it takes their consumer rights away, simply by pointing to the pirates as their reasoning. Kind of like "Well yes we're tapping your phone....but it's to stop the terr'ists!"
DRM has allowed developers to add weight to their "licensing agreements", which meant fuck all without control of the content before. In the olden days of copy protection, it was truly about verifying the customer bought the product, by making them rely on the things that shipped with the game to play it.
Now, we have software installed, servers that track our behaviors, our IPs, our registries, our installs.....
Like I said, DRM is about defining the rules of the marketplace. Not enforcing them.
