@elinora-froach That's not "the issue", that's "the consequence" of copyright laws. You're still not accounting for what's the purpose of copyright laws. It, together with patent law and trademark law, enables treating ideas like property, analogous to owning an apartment, house, a hotel, or a company. It's why those three together are called "intellectual property rights"
A proletarian worker like a miner or a librarian going to work, she is trading her time spending performing labour for money. Fundamentally this means that if she stops going to work, she stops getting money. It is in her interest to maximize the amount of money she gets out of a month of work, and minimize the amount of money she spends on purchases.
An ~independent writer~ when writing a book is indeed performing labour - but the end goal of performing that labour is creating an intellectual property. Once this intellectual property is created, it is in her interest to maximize the amount of money out of it.
How do you monetize a property? By having people pay admittance at entry. For hotels this means getting people to pay for an access to a hotel room. To maximize the amount of money you get, you can either get more people to rent, or increase the price of access per person per night. It also means guarding your property so people are less likely to overstay and avoid paying you.
Now, the contents of the book is surprisingly easy to copy. Bad news for the property owner. How can she guard this property? Why yes, with intellectual property laws. Its purpose is enabling the capability for the property owners to send cops at you if you attempt to do so.
When the original poster points out the obvious fact that stems from this that it is opposite of her interest to maximize the yield for the property owners and the obvious problems that result from endless rent seeking of intellectual property, she gets harassment and guilt trips from people who go "hey, I take offense to this, I just own a small house in the middle of nowhere with no water or electricity, I get very little money out of this entire whole landlord thing, how am I supposed to get money out of it if people keep squatting here?" or "hey, I am cooperating with the rental property company, but they take so much of the money I get off the rentals"
(the fact that they could be getting paid for the labour itself rather than the property is very much ignored)
