I agree with vinceguidry's comment.

Perhaps I wasn't clear - of course you should be careful about naming things well (one of the hardest problems in CS, right? :P), but using consistent terms, case and the like is one thing.

A large part of CSS naming conventions is doing more convoluted stuff such as business-page__contact-form__submit--disabled, just because there are other submit buttons on your website and you don't want some styles to clash. This is the part that is abstracted away by automatic solutions.

If your favorite programming language scoped all variables globally, no matter where you defined them, sure you could prefix them with the name of the current function to solve your problem, but it'd be painful and error prone.
