It's easier to move a book from one shelf to another or to move it from one residence to another. You can pass them along without encumbrances like licenses or TOS or you can loan them to a friend and not have it tracked.
Easier to lose it too, or to get it destroyed. And harder to loan it to more than one friend at once, or read it yourself while someone else has it.
You may prefer paper books, but it's a subjective choice dependent on how much you value some things vs others, not clearly better either way.
Good for you, you'll be mindlessly protecting your interests against all that nasty DRM and protections that publishers and distributors will be thinking up. I have better things to do with my time, like read.
So, physical books just appear in your shelf, right? No time required to go to a shop, or pick them up? Well, personally I don't have such magical abilities, so getting a physical book takes me orders of magnitude more than un-DRMing them. Or would, if I bought DRM-ladden books, which I don't.
Remember in the US at least the DMCA allows them to protect their data with whatever means necessary and if you agree to that, then you're bound to it. Do you read all those license agreements? usually there's a clause "You agree to allow us to make changes to this agreement..." Which is usually a one-sided affair, regardless of mechanism, paper books don't have those strings attached leaving your nice little words aren't really worth the paper they're published on.
Yeah, I print those agreements and wipe my ass with them. Who the hell cares?
Not that I live in the US, anyway, but even there, when was the last time someone was convicted for breaking the DRM of their own books? I'm guessing "never".
Sometimes paper, the lowest common denominator for publishing, is the best format especially if you want to review it at your leisure without having to download an upgrade, remember to charge your e-reader or not get inundated with ads or tracked on what you're reading or have in your library. I'm not saying that open source e-readers are bad, I'm just saying the tablet your using (iPad, Android, Kindle et al.) has tracking on it, so that not necessarily your reading may be tracked but your reading list might be.
Yes, sometimes paper is the best option. I certainly don't disagree with that, nor did I ever, so I'm not sure why you're saying that.
As for ads and tracking, it takes five minutes to find a reader that has no ads or networking (kinda hard to track you with it).
If I want to read my copy of the "The Anarchist Cookbook" I don't certainly want the government knowing that Amazon or Google let them know I was reading it on my e-reader or that it's stored on my tablet (even with name obfuscation) That's one of the liberating things about a book, it's yours, nobody knows if and when at all if your reading it and you can hold it that is until some fascist decide to take it away from you.
Yeah, I agree that paper books are better if one wants to read subversive literature, especially if you live in a police state. Thankfully, you don't lose that ability even if you read most things on ebook readers.
