Making copyright/IP protection last for a very long time defeats the purpose of it entirely.
If you want indefinite protection, you don't share your idea. You get to realize all the benefit, but you run the risk of your idea being independently discovered or stolen.
In exchange for offering you a monopoly for a limited period of time, which guarantees that no one will steal your idea or benefit from independent discovery, then we require that you give your idea to the public after a set time. Thus encouraging progress, from which the public benefits, and at the same time, ensuring that that progress does actually benefit the public at some point in time, rather than one person.
