I think you have a very severe misunderstanding of the Wikipedia Library, which I have access to and frequently use. The WPL allows active editors in good standing to access paywalled sources.
- You must have an account which is 6+ months old, has made 500 edits, has 10+ edits in the last month, and is not blocked. (an extreme minority of editors, let alone readers.)
- You must first apply to gain access.
- For publications with limited subscriptions, you must individually apply on top of your WPL access.
- Critically: the WPL does not host any of these publications. You are taken to them via a portal and given an access token.
I can't emphasize enough how absurd this comparison is. "Solar farms exist; building a Dyson sphere would be basically the same thing. Let's get to work." And the thing is: I wish you were right.
Edit: That said, if you ever need copyleft material, we do maintain Wikimedia Commons for media generally and Wikisource which is a transcribed digital library of free sources. Much narrower in scope than this, but I highly recommend them!
