Make something that can't be pirated if you don't want it pirated because if it can be it will be,
Herein lies the rub. It
can be pirated. No matter what it is or how it is released, if it is intended for mass distribution, it can be copied. The distribution channel of the original is irrelevant. Vinyl was being ripped and copied to 8-track long before streaming audio was around.What is new is not that things can be copied, but that the copies can be distributed widely anonymously, and virtually without consequence from locations beyond the reach of the law.
The digital tape recorder was never really available in this country (USA) because the audio industry convinced congress that they would lose their shirts if perfect copies could be made, and hassles over what type of copy protection circuit could be built into those machines before they could be marketed here. Copy protected (DRM) digital audio has been largely abandoned because it made the songs unusable for the user or was so easily circumvented that people got ripped versions that did not have DRM to make life easier, not just because they were free.
The inescapable conclusion to your observation is that since you cannot record anything in music that cannot be pirated, then you should not make anything. Or rather you should not make anything that you do intend to make money. The artists who seem to be the most sanguine about the inevitability of piracy, are those who can fill a stadium with fans willing to spend 1000 times the artist's piece of the cost of a paid download to watch them sweat.
Most musicians will never have that business model. The dream of being discovered on a download site and elevated to super stardom is like the dream of hitting the lottery. Clearly the guy who spent so much time and money creating a sample library of obscure drums should not have expected to break even. Increasing his costs by trying to distribute it in a secure way might have actually worked for him. It would probably not have netted him much more. But only because the demand for his product is so low that it is hardly worth the trouble to steal. Regardless or how you present your recording to the world, if it becomes popular, you will lose a lot of potential revenue to pirates.
So you can ridicule him for not anticipating the pirates, and say it is like complaining about getting wet when you jump in the river, but it is absurd to advise him to take the ferry if there is none. And one thing this thread has demonstrated is that there are people who are not making millions in the business, who are suffering real harm from the pirates.
