Sure you would - maybe not for cold calling new prospects, but when I was doing consulting, I would get asked for my resume as part of my potential customer's due diligence process on me.

And those people would actually read it, because they already knew me and were trying to understand my background to decide whether or not to bring me on to a project. Unlike recruiters or hiring managers who are often just looking for a reason to throw a resume in the trash to thin out their crowd of applicants.
