If that isn't good enough, do without. Just because you want it doesn't mean *anyone* is under any obligation to make it available to you. It isn't ethics; it's the free market, stupid. There are lots of books from those in current publication to those written by authors long dead that aren't available as an eBook. Just because you want one of those in an eBook format doesn't somehow justify pirating a copy; nor does it justify pirating the book in question.
Back atcha. Just because you want money for every single copy doesn't mean *anyone* is under any obligation to give you money when they can make a copy without involving you. That would be the 'free market' in action: the natural cost of distribution is zero, and propping it up above zero--particularly with legislation, something the typical libertard otherwise equates with scabies--is the interference with the market's actions. It's not the 'pirate' (a stupid term propagated by stupid people - copyright violators do not normally interfere with commercial shipping) who is obliged to justify his action of copying, it's the copyright holder who is obliged to justify why preventing copying is a better thing for the economy as a whole. (Which can never be done, and therefore, copyright holders will tend to fall back on whining, tattling, and pulling at the skirts of the legislature.)
Grow up and quit whining that the world doesn't give you everything you want.
If you can't see which side is simply doing what the technology allows, and which side is whining that advancing technology is interfering with their vast desire for precious precious money, it's you who needs to do some growing up.
