It's definitely not a universal scenario that the agency can produce 100% of the content for the client. Sure the content should be part of the planning and budgeting up front, and the agency should do as much of it as they can. But a common example of where you may need content from the client is a hotel that wants to do a new photoshoot for their new website. They know that photos are incredibly important to their marketing, they often have a preferred photographer they want to work with directly, even if you're local and offer to conduct the photoshoot for them, they can probably do a better job producing those assets than you can because they know their property inside and out.

That's a classic case where you have to depend on the client for content and a tool like Content Snare might be useful.
