I totally agree. Frameworks are needed for large projects. You either use an open source one, or build one yourself. And usually, the former is greatly preferred. However, if you're a frontend dev, you should understand VanillaJS. Just like a systems programmer should understand assembly and C. Also, there are some situations where you won't need a framework. Knowing VanillaJS and using frameworks are obviously not mutually exclusive.
