7 years as sole seller of your own creations, and leave to apply for 7 more years - IIRC - were the terms under Queen Anne's Statute protecting creative works (approximating copyright). Then works are freely available to all, and deposit requirements meant preservation and access was afforded.
The alternative is that corporate entities get all the money and creators get all the costs and the pubic domain gets nothing.
There's a lot wrong IMO with Western IP laws (I don't know about others) but the concept of them is not wrong.
There's specifically no protection for information in patent and copyright laws (database rights, eh, maybe ...).
