The thing is, you're not selling a product, you're selling an idea. An idea entombed in a product, but still an idea.
If someone made a chair, it's a definite product. I can touch it, sit in it, and sell it. If someone wants a chair like that, they can
1. buy the chair from me, at which point I'd have to make a new chair to be able to sell to a new customer. or
2. copy it, make a replica of it. With enough time, materials, equipment and skill, it can be done. They get their chair, and I still have mine to sit in and sell. They can also
3. Steal my chair, in which case they have a chair, and I have none. The time and materials I invested in it is gone. I'd have to make a new one from scratch.
The problem with an idea is that, at the core of it, it's just data. And computers are truly excellent at working with data. So with option 2 above skill, time and materials mostly disappear. The only thing left is equipment, and almost everyone got a computer. It's still not stealing, but it can be a devaluation of the product you are selling (I say can be, because there are cases where product value have increased as a result of rampart copying. Adobe products, Microsoft products and this story are examples of this).
If someone said "I've now made this chair, and shall now get paid for everyone sitting in it, until I've been dead for 75 years!" people would think it nuts. If however, he was offering a service (a place to rest, which included a chair) then it would be different, but just the chair, wherever it happens to end up? Hardly. Yet, "I've now written this book, and shall now get paid for everyone reading it, until I've been dead for 75 years!" is perfectly acceptable. Now, think a bit before you say something. The book is sold as a product. Yet, unlike other products, when bought it's not ours. I'm not free to for example publish pictures of it. I can't improve it and sell the better version (AFAIK). It is sold as a product, yet it is not. This is, I think, one of the core problems with copyright as it is now. Intellectual property (*cough*) is cherry-picking advantages both from the product side of things, and the service side of things, and it has allowed itself to grow too big. Into a completely new thing, which the world is still struggling to get a grip on. And thus you see where some of the completely crazy stuff happening are coming from.
All this goes double and triple when applied to music and software. And I'm producing software myself, so I see your point. I'm not saying copyright needs to go, I'm saying copyright in this age is something new and unbalanced. Before copyright, people lived by performing their ideas, whereas they were stories or music. They created books containing their ideas, before mass production was possible. Now, any idea can be replicated across the entire globe in a matter of hours, by more or less anyone, at little or no cost. And people expect to live off their (or someone else's idea) idea for the rest of their life - and then some. The times ahead will be .. interesting.
Why do people complain when the government limits the choice of Internet providers, but the pirates removing my ability to choose my own business model is somehow a good thing?
You forget that you're not free to choose just any business model. I'd like a business model where everyone owning a computer paid me $1 per year as license to my software, but I doubt that would fly (hell, I'd even stretch to $.5). Here it is not the government or the fat cats restricting your business model, but your customers. These who are copying your books are people who actually want to read your story. They are your target, your potential client. They have a different view of how to get your books than you have. Think why, and think if there's any way to move closer to what they want, while still getting yours. Is it the price? Convenience? The fact that they want to check out a new author and see if they like the style? All of these are factors that can be changed. Prices can be lowered, it can become easier to get your books legally (are you on kindle, for example?), you can release some chapters or even complete old books out for free (with info on how to easily buy more of your work).. The point is, there are a lot of factors in it, and taking the line "Dey be stealin my stuffies" and ignore everything else is not really helping.
