I think that Mrs. Bennet might be so obsessed with marrying her daughters off in order to make sure she has a future. After her husbands death she will have no claim on the land or house she presently lives on because the entail will fall to Mr. Collins and she wil be sent off the land. She could however live with one of her married daughters if she can marry one of them off. Mrs. Bennet's obsession with marrage for her daughters is probably more excusable than you would expexct.
