That works if you have content that you know is an email address.

If you have free-form content, and need to identify email addresses in it, then you can’t just email every subset of that text.

That's what validation is. You're talking about finding email addresses, which I agree that regex is relatively OK at doing, but there are still lots of edge cases in the spec that are irregular.
