I'm not saying the futility of their efforts is the reason to change copyright law (although it should be possible to turn the argument your imagined lawyer comes up with around) - I’m saying what they are doing is futile, hurts more or less all of humanity AND copyright law is broken and does not serve its intended purpose anymore.
It sounds like we both agree the countermeasures were futile. I guess my comment can be refactored to "The Law allows you a play-the-victim card, which you can't do in tech". I would reform your statement to "copyright doesn't serve its original intended purpose", but serves its de facto purpose just fine: keeping corporations raking in profits. they dont need to stop all countermeasures to accessing Anna, or whatever avenue pirates use. They just need to keep netflix and all other big name content providers/broadcasters/record labels paying their royalties (at the expense of artists and support staff) for as many decades as possible. If you look at it that way, copyright is working fine.
