How can I hide sections in Layouts?

I'm trying to simplify the "Accounts" layout for our sales team, and because we bill via email/fax and don't send physical products, I want to remove the "Address" information from the Accounts view.

When I try to "delete" the section, it says deleting it can cause an "invalid data error" - There's no explanation of what this error is, or how it will effect me, so I don't know if I can remove this feature. Please let me know if it's possible.
