What they usually "forget" to tell you is that your IP is absolutely worthless if you don't have the resources to defend it in court, which in turns actually advantages freeloaders who either have relatively low costs to sue (patent trolls are basically an example of this) or enough money that they don't feel the pain if they lose.
The current system basically incentivizes suing over IP NOT creating it.

Overall, IP seem to be a massive mistake.
Copyright terms longer than a reasonable 5 years are only benefitting Disney and the other big copyright cartels.
They are not serving the purpose of copyright: To encourage creation.
