This is a dubious argument, as you assume that those people who copy it would have never paid for it, and, perhaps even more importantly that those who DID pay for it would have paid for it even if they had the option of just copying it.
And how do you cover the original cost ? Through the first sale paying the spent time and resources ?
That would mean the first (and only) buyer of, say, Oracle would have to pay a few billion dollars. At which point nobody would buy it, and Oracle would simply not exist.
