It's a problem because it's necessary to understand biology and medicine. It directly affects important public health issues, most visibly the development of drug-resistant bacterial species. It's also fundamental for archaeology and palentology. The point of pre-college schooling is to provide a broad base of knowledge, both for everyday functioning (literacy, math, etc) and to act as a foundation/inspiration for future learning. If kids aren't exposed to anything beyond basic literacy (enough to read street signs and product labels) and math (enough to be able to pay for things) they might function as adults but it's much less likely. So while evolution isn't needed in everyday life for some people it's certainly more useful than bible study.
