I see what you mean. The paragraphs you cited certainly showed why LR tried to persuade Anne to consider Mr Elliot due to his rank and future titles. It also goes in line with what others have mentioned before, that LR would have encouraged Anne to marry "well," even if it will end up in a loveless marriage.

I can see LR's reasoning that it would be better for Anne to have a decent place to stay and be taken care of in her old age rather than to marry for love and die in poverty. That also tells me that the gulf between rich and poor was so wide in that period of time that it was almost unthinkable for LR to allow Anne to choose love over wealth. It does explain why LR thought a union between Anne and CW in 1806 would be "a most unfortunate one" (ch 4).
