Just because you have the ability to work with individual atoms doesn't mean that you want to do everything that way. There are two common situations where a different approach is needed.
First, you often need abilities that can't be built into a nanoscale device. Nuclear power is one good example - a nuclear reactor has to be big enough to capture its own radiation output, or you don't get any energy out of it.
Second, it is often more efficient to use larger machines. If you want to move a ton of matter from point A to point B, a truck is a lot more efficient than a horde of nanobots.
Real nanotech won't use nanobots for everything. It will use a combination of normal and molecular manufacturing techniques to build whatever tools are best suited to the job at hand, whether nano-, micro-, macro- or megascale.
