CSS is not a programming language. You can't think about it the same way you'd think about your backend code or even client side JS. The global namespace is by design. It's a feature, not a bug. The whole point is to think about the Cascade. You go from vague to specific and that way you have entire classes of elements with base styles and specific components have additional styles attached.
CSS modules is a cool idea but I don't think there's anything wrong with CSS as it stands today. When you work in any language you need to understand and work with the language you have and I think that a lot of criticism of CSS boils down to "CSS doesn't work like this other language/paradigm I know and like".
