I'm certainly not pushing for socialism or anything like it. I'm closer to libertarianism than anything. To me, the default answer for "should the government be involved in X?" is "no." To answer "yes," I want something pointing to either an "inalienable right", like "freedom from murder," or a clear public good, like "we all benefit if you aren't allowed to dump nuclear sludge in the storm drains."Sounds like I'm in good company. That makes me happy.
I think the key thing we disagree on that I don't see copyright ownership as one of those inalienable rights, and you do. And I don't see indefinite copyright as a clear public good, either.
First, I think that people should be free to make a contract that states, "I will let you read this thing I've written, if you agree to certain conditions" (and those conditions could be anything - don't write fanfic, don't distribute, you have to do 50 pushups, whatever).
Then, copyright is just the government saying, "For the sake of convenience, here is the default contract. If you want something different, you can always explicitly opt out of this, and optionally specify something different."
I'm really interested to see if you buy this rationale for copyright.
Whose good is intended by said progress, if not society's as a whole?
I think the intention is to "promote the Progress of Science and useful Arts," which does benefit society, but indirectly. I think if the intention had been to promote the public good, they would have said "to promote the Good of the Public" :P
If you still think this is unclear, you're trying too hard (but let me know and I'll explain it differently.) Of course, you may disagree, but I want to make sure you understand what I'm saying.
As to whether it matters, it's the only existing legal rationale for copyright in the U.S.
True, I guess, but I'm not interested in how the current law can be interpreted ("legal rationale"); I'm interested in how things ought to be.
