I don't read it the same way. Anne seems to accept her father's displeasure and that his view would be that the marriage is a degrading alliance, and does not ignore it.

In Ch 4 we have "Such opposition, as these feelings produced, was more than Anne could combat. Young and gentle as she was, it might yet have been possible to withstand her father's ill-will, ....."

I see more of the irresistable force meeting the immovable object than Anne simply shrugging her shoulders at her father's angst.

It is only when LR also takes the same line but expresses other considerations that Anne's opposition is overwhelmed.
