Kobo, on the other hand, say that you're not even allowed to let your spouse or children read your books.

The first link in spoiler is highly interesting.

In terms of use, you have purchase a copy of a book with us, and it is your copy. You may authorize any one you wish to read it, but that person's device must be registered to your account to do so.

He specifically says that I purchase a copy, now my copy, of a book that happens to be permanently linked to my account. I wonder if that is legally how it is and the licenses are a mere container or construct that allows me to use that copy without breaking copyright law.
