So you think Chevy should go after car thieves and sue them?
There's an entity in existence which was created to deal with illegal activities. It is not the producer of whatever it is getting stolen.
That's why you ignore piracy. The FBI will handle it. It's not like the developers can do anything about it.
We're not assuming it goes away either. What we're doing is catering for the only people we need to cater for and not doing the FBI's job for them.
Seriously are you forgetting that we have a taxpayer funded entity for handling piracy? Because what you're saying is no different than Chevy trying to sue car thieves. If you're a developer you have to take it as red that some people will pirate your game and that nothing you can do can slow them down. That's why you instead focus on your honest customers. They're the ones that deserve a developer's attention because they're the ones funding that developer.
When someone steals a car, they're stealing it from an individual (who also doesn't have the cash flow/support/resources that a large corporation would). So the "developer"(Chevy) has already been paid and taken care of, out of the equation, and the individual is out the cash. When you pirate a game, you're stealing directly from the developer. A more reliable example would be people literally going to the Chevy plants and stealing cars right off the production line. If that were happening, you bet you would see FBI/other agencies involved.
You're simplistic views on the effectiveness of law enforcement are also off-base. Internet crimes are very hard to track, prove, and enforce. Why do you think pirating movies and music is so rampant yet barely anything is done about that? Sure, the RIAA sued a handful of 12yr olds and some 80yr olds--but that was just to send a message, really. Even then, it cost them 10x more than what they got. The FBI, or any other local or national entities, really don't have the resources to take on and handle a burden like that. You'd need a very large dedicated force that is put in place to take down individual pirates--and even then, what would you do? Fine them $100? $1000? Remember, in the end all these entities are burdened by the very tax payers who vote them in. Besides, the last thing I would want is more government agencies wasting tax-payer dollars.
So you can see, it only makes sense for a developer to try and protect itself & its interests, and you basically ask want to pass a law that fines them double for simply trying to stay in business??
You will have absolutely no creative marketplace in your kingdom.
