Nothing to say about the last two arguments, but this:
- It is technically theft
...is just bullshit. Theft is illegaly taking a property or service from a person with the intent of depriving them of it. When you're pirating, you're essentially making a copy for yourself. In doing so, you're not taking the original book, nor are you depriving the original owner of said book.
"Piracy is theft" is just some heavily regurgitated nonsense from the early 2000s that has been debunked many times over. It needs to die, because it is just objectively not true.
