They must be compensating for something.

The Delta IV is not man-rated nor can it easily be modified to be man-rated
Also the burn profile of the Delta IV sustains more than a 6 G acceleration and that is a bit high for human missions.

For reference, the Shuttle went in to orbit with a 3 G profile. It is a trajectory thing.

If any non-man-rated vehicle would be modified to be Man-rated, I would imagine the Atlas V is probably the best candidate. But it still will be expensive, perhaps too expensive.

A sense of identity.
