Exactly.
Copyrights are ridiculously expansive, and Fair Use defenses steadily narrowed. The reality is that the primary limiter on copyright enforcement has always been the practicality of detection and notice. Secondarily is the fact that in some jurisdictions, most notably the U.S., remedy is limited to an injunction and actual damages (e.g. lost licensing fees) if the work was not registered prior to infringement. (Because for most works, such as a resume, actual damages can't be shown--the standards for calculating damages are pretty strict--all you have is an injunction.)
If such technicalities were to be magically lifted there'd probably be much more pressure to reduce the scope and duration of copyrights. Conversely, that such technicalities exist goes a long way in explaining the wide scope, and to a lesser extent long duration, of copyrights.
