The only way here to accept that content will be pirated but trust users to do right thing as well.
Many content creators put off users with their stupid DRM implementations. I remember buying a game for some $34 in 2008. But that game had 5 copy limit. Now I am what you can call a "regular formatter". Formatted PC twice, changed laptop and now I do not own license to that game.
Let user make copies, but trust that they won't copy them further.
But the issue here is not only the end users, but also publishers and others who could potentially make a business out of selling this authors work without paying him one cent. There is in my opinion little reason to want to get rid of ones copyright, it's better then to declare that it can be used freely without charge for non commercial use for example. Or if the intention is to sell it, simply not using any DRM schemes at all.
