You're making some big leaps in your interpretation vs what's actually being said. I don't see a single comment saying she should sell because money is all that matters. A few comments are saying if she sold it to a housing developer that would create more housing - which is objectively true - and then asserting that more housing would be a good thing given the housing shortage - which is a value judgement you are free to disagree with, but not at all the same as saying profit is all that matters.
