As a student that uses Google scholar quite often "almost everyone" is a lot lower than you think it is. At least in computer science and related fields, I have to use my schools access to journals almost every time.
That's odd. I'm a computer scientist who uses Google scholar quite often, and I can't remember when I last needed to read a paper which Google couldn't find for me.
Maybe the situation is different in my fields (algorithms and cryptography) than in yours?
