Re: You have to convict the current owners
Most crims are deterred by prison and high fines but some crimes are rotten to the core and will need to be exterminated to end their reign of crime.
Err, no. Taking a personal example, I am not deterred from committing murder by the likelihood of jail, I do not want to commit murder because this would seem (to me) to be ethically wrong. Piracy is a less ethically extreme example, and I suspect the deterrence comes more from the need to fit in socially. It is the fear of capture (and hence the likelihood of being caught) that determines crime rates, rather than the punishment.
Your conclusion does not follow. There are other ways to prevent those who would commit crimes from doing so; jail would seem an obvious example.
I'm not sure your post deserves such a reasoned response; the first 3 sentences seem rational but from then on it's nonsense.
