Unit tests cannot fulfill the role of acceptance tests.

To further elaborate...

Unit tests they are useless in proving that the right thing is being constructed. They only demonstrate basic correctness.

Unit tests won't show whether a bungalow is correct, or a block of flats is correct.

They'll show if the nail is correct. The nail does not care if it is used in a bungalow, or a block of flats.
