But you can pay someone to make you a copy of the journal, or to print the journal for you. Even then, I would argue that you're not really paying for the right to read the journal. You're paying for the right to read the text that you downloaded. If you're willing to do that, you can read the journal for free. There's no reason to pay. Even if you were going to subscribe to the journal, you can just download a copy.
This is a pretty basic free-market principle. I'm not saying that an open access journal is inherently ethical. I'm saying that people are free to choose, and people are free to choose what they read and how they read it. People who can't afford a subscription can buy a paper copy of the journal. People who want to read for free can read the text that they downloaded. People who can't afford a subscription can pay a third-party to print the journal for them. 827ec27edc
