You might know this already, but you can also just ask the authors, and they'll often send it to you. Definitely not as convenient as Sci-Hub, however.

I'd definitely think about doing exactly that if I were after a new paper but most of the stuff I'm interested in is in history, law history, linguistics and diplomatic. Those papers often precede the Internet, not even mentioning dead authors.
