Bigger weapons will not help against decentralized guerrilla individuals with nothing to lose. They will only hurt the innocent.
When the innocent casualties of war exceed the damage inflicted on the enemy, something has gone terribly wrong.
In the First World, anyway*, the fight isn’t about ownership, it’s about perceived fair play. If you don’t believe that, look at the success Louis CK** has had with his recent comedy video sale, and the success various artists have had on Kickstarter. If the consumer thinks you’re a giant corporation out to screw everyone, they will steal your product and justify it to themselves. So, the answer is to change their perception of you, not to threaten them with yet another set of rules and regulations and penalties. They WILL steal your stuff. It’s as easy as pie, and you can’t stop those who want to do it any more than you can stop the rain. All you can do is make them like you enough to treat you with respect. Is that “right”? No. So what? You can either do what works, or be right and lose everything.
* Piracy in third-world countries is unstoppable, and it’s pointless to try. They aren’t going to buy your product at a rate you like no matter what you do, so you are losing nothing. The people don’t know you, don’t care about you, and will never see that some whiny rich person in a first-world country should get any more than they already have. If your morning coffee costs more than they make in a week, you lose the mind-war. As a side note: the more you spend trying to stop piracy in places where it has no effect on your bottom line, the more you charge the average First World consumer, and the less inclined that consumer is to pay your inflated rate. Not to mention the bad PR/image costs.
