That sounds more like a case of a bad framework (and bad language) than an argument against frameworks in general. Even if you only ever use a language's standard library, different projects will use different parts of it, so there's always going to be some new things to learn when switching projects.

Use an environment that matches what you want to learn, and one that promotes good development practices. But given how much modern programming is framework-based, that likely means using a framework.
