The original framers of the constitution recognized this at the founding of the republic.
"The Congress shall have Power To...promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries...."
Nobody objects to people having the protection of a limited copyright so that they can profit from their ideas. Everyone - including, I'd argue, most copyright holders but excepting apparently their very successful lobbyists and tame congresspeople - agrees that "copyright" != "rights to exclusivity in perpetuity so that person and their heirs never have to work again".
You do realize that SCOTUS has ruled that limited times is subject to the "I'll know it when I see it" rule of being out of bounds. They have yet to see a number that they've declared limited. Of course, it's all about perspective. In a geologic time scale, then 100 years is very "limited".
What I would like to see is a "short-circut" timer based on dates of publication. If a work is not published at all (made available to the public in some form), then it gets a shorter protection time. Once a work is published, the date it is no longer available (ie, the book goes out of print, the software is no longer sold), then another timer starts - you have X amount of time to re-publish it (say 10 years) or it passes into the public domain.
