Why? Why is copyright different from any other area of the law? Anybody can sue anybody else right now, for example claiming that some sort of service has been performed, and the situation would be the exact same. The use of criminal law would be a gigantic drain on already scarce public resources, why waste them on something trivial? If anything, suing for IP infringement should be easier - so that everybody can do it, and not just those with 10k cash up front and several months or years time to wait out the result. The key to an effective copyright regime is a way to enforce rights. That way needs to be cost-effective, fast, accessible to any sort of rights holder, and needs to put control into the hands of such rights holders. Leaving enforcement up to a prosecutor (who will need to weight such cases with e.g. murder and rape cases!) is or does neither of those.
