That was my initial though, in CSS you can reuse classes and other code, right? But in react components can also be reused and/or extended. I would say, that using CSS makes managing big project way more expensive than using React/something similar. It's not intuitive, but you don't have to believe me, Facebook and Instagram have pretty big codebases and react with inline styles is their solution - while it's not an argument per se, it's a hint that this approach may work.
