The second looks at who benefits from copyright protection for things on the internet and whether it makes much difference in the incentive to create link here. Most violations occur on the internet where the returns to the creator for the high earning books and movies have become enormous; that constitutes, if anything, an incentive to produce less.
In short, why should public moneys be spent to guarantee ever higher, not to say exorbitant, returns to copyright owners? This is not the sort of argument lawyers will find attractive, but why trust their judgement since they are big gainers from enforcing prosecution. Better not to have the public pay for enforcement and make the lawyers earn their generous take.
