Things every generation ever has said.
Things which have been true for every generation! Well, there were some setbacks scientifically, but those people generally had to deal with a lot of strife so they weren't really wrong.
There's no need to have a short copyright term (though the recent extensions are silly),
Right, and all I'm doing is arguing against the extensions.
instead we need to change what copyright means, so that you can't restrict the distribution or prevent derivative works
I'm not seeing why your plan is better than my plan.
I see no problem with the creator continuing to profit for a long time from some creative work,
I see two problems. The first problem is a problem for society. The purpose of copyright is to promote works. But permitting someone to profit from a long time from a work doesn't promote more work, it promotes resting on laurels. The other problem is that once the material enters the collective subconscious, it really ought to belong to all of us. If you can't get it out of your life, it shouldn't be permitted to belong to a corporation. That doesn't actually benefit anyone except the corporation's shareholders. And Disney has been making damned sure that doesn't happen for quite some time now.
The problem comes when copyright blocks further creative progress, and that is fixed by mandatory FRAND licensing.
I disagree strenuously. It is fixed by reasonably copyright terms, where those terms are much shorter than a human lifespan — as they were originally. The terms were not extended to benefit the people, but to benefit corporate interests.
