> legal systems don't need a technical solution to enable it
They absolutely do. Without technological solutions, they don't even have a snowball's chance in hell of even so much as identifying perpetrators of copyright infringement. They can't stop it even with technological measures in place. In order to enforce copyright, they literally need to end computing freedom as we know it today. Computers gotta come pwned straight off the factory so we can only run software that they approve, so that they can reject software that copies their bits.

Let's discuss the law then. I propose that copyright should stop existing altogether. Simply because laws encode the customs of a people and copyright infringement is absolutely one of those customs. It is normal and natural to infringe copyright.
You infringe copyright when you download a picture or video from a website. You infringe copyright when you screenshot some social media post. You infringe copyright when you share something with your friend via messaging app. You infringe copyright when you make some funny meme by editing text into some popular culture picture. You infringe copyright when you download a copy of some blog post so you can read it later. It goes on and on. Pretty much anything you do infringes copyright. I've seen people arguing that fucking memcpy infringes copyright. It's mind boggling and never stops.
People do all of this stuff without even realizing it. How could it possibly be illegal? The only reason I can think of is constant lobbying by trillion dollar corporations.
