I agree with you but the customer is always right, and to a certain extent I
will give her the benefit of the doubt. She wants to be able to filter the
form and various reports by these calculated columns, so she wants to see
them there in the table. Besides, we're probably going to upsize the app to
SQL Express fairly soon, where I can have the best of both worlds, i.e.
genuine calculated columns that consume no disk space but are logically
"there".

Your point is valid and I agree with you, but the customer wins in this
case.
