Copyright law certainly has major issues, I'll agree, but it does not prevent you from sharing things if you want to, provided you created them or own them.
Fun fact: in many places, you actually can't. You can sign over copyright to someone else, or you can give anyone permission to do whatever, but many legal systems have no concept of "disclaiming copyright". You have it, whether you like it or not. This is why it is frequently advised against putting "I put this code in the public domain" as your open source licensing term. It has no legal meaning in many places, which means that it's not properly licensed at all (i.e. full copyright applies).
I do release everything where I have copyright under free/libre/open terms. But that's not enough to cover the concerns I'm referring to.
I'm saying copyright should be eliminated because it's in the public interest to have more open access (both plainly and for derivative use) to all resrouces
If you give your car away to someone else, why would you be mad that you can't just use it at random times?
The authors have had the solution in front of them from the beginning. They've been free to send out free copies from the time they finish.
But if they want the advantages that come from journals, well, someone is going to need to pay for them.
So let us create a website that for a given paywalled URL automatically emails the authors for a PDF. ;-)
