If the copy becomes distracting in the design then you are doing something wrong or they are discussing copy changes. It might be a bit annoying but you could tell them that that discussion would be best suited for another time. At worst the discussion is at least working towards the final goal of your site where questions about lorem ipsum don’t.
Typographers of yore didn’t come up with the concept of dummy copy because people thought that content is inconsequential window dressing, only there to be used by designers who can’t be bothered to read. Lorem Ipsum is needed because words matter, a lot. Just fill up a page with draft copy about the client’s business and they will actually read it and comment on it. They will be drawn to it, fiercely. Do it the wrong way and draft copy can derail your design review.
Fashion has become a joke. The designers have forgotten that there are women inside the dresses. Most women dress for men and want to be admired. But they must also be able to move, to get into a car without bursting their seams! Clothes must have a natural shape. Elegance is not the prerogative of those who have just escaped from adolescence, but of those who have already taken.

Websites in professional use templating systems. Commercial publishing platforms and content management systems ensure that you can show different text, different data using the same template. When it’s about controlling hundreds of articles, product pages for web shops, or user profiles in social networks, all of them potentially with different sizes, formats, rules for differing elements things can break, designs agreed upon can have unintended consequences and look much different than expected.
This is quite a problem to solve, but just doing without greeking text won’t fix it. Using test items of real content and data in designs will help, but there’s no guarantee that every oddity will be found and corrected. Do you want to be sure? Then a prototype or beta site with real content published from the real CMS is needed—but you’re not going that far until you go through an initial design cycle.
Lorem Ipsum actually is usefull in the design stage as it focuses our attention on places where the content is a dynamic block coming from the CMS (unlike static content elements that will always stay the same.) Blocks of Lorem Ipsum with a character count range provide a obvious reminder to check and re-check that the design and the content model match up.
You made all the required mock ups for commissioned layout, got all the approvals, built a tested code base or had them built, you decided on a content management system, got a license for it or adapted open source software for your client’s needs. Then the question arises: where’s the content? Not there yet? That’s not so bad, there’s dummy copy to the rescue. But worse, what if the fish doesn’t fit in the can, the foot’s to big for the boot? Or to small? To short sentences, to many headings, images too large for the proposed design, or too small, or they fit in but it looks.
