Imagine a world where you can click on references in your paper and have them immediately come up, like the rest of the web. This can be done today:

Always provide a DOI-style link, for example: https://doi.org/10.1088/0029-5515/30/2/001

These can be easily changed to actual working links with a simple browser substitution rule: replace the "doi.org" with "sci-hub.se" or whatever.
