Funny, that didn't seem to be a problem when I opened my Christmas presents last year.
I don't understand this idea that it's somehow inherently wrong to receive things without paying for them. Should we outlaw soup kitchens for giving away food when restaurants are trying to get people to pay for meals? No? How about libraries? I didn't pay for the novel I read last week, I borrowed it from the local library.
I do understand (and agree with) the idea that it's wrong to deprive others of their property without their consent. After all, if you steal my books, I can't read them anymore.
If, on the other hand, you sneak into my house while I'm away, make copies of my books, and bring home the copies to read yourself, I might not even notice (unless you broke something or left a book on the wrong shelf).
