We need Elsevier's revenue to decrease enough so that some benevolent billionaire can buy it and make everything open access.
Elsevier's has plenty of ways to reinvent itself make money. Scopus is a good search engine and libraries would be wiling to pay for it unbundled from journal access.
Isn’t this a regulation problem? So much stuff that is funded with government money (partially or fully) ends up pay walled. Can’t governments regulate to stop that?
The US govt already requires publicly funded publications be shared publicly. Some agencies like NIH and DoD have their own archives you need to put the article in. The law allows up to something like a limit of one year paywalling.
