Women that talk like this aren't even worth a response. It's clear they are in rebellion against God and man. If you sacrifice for a woman that won't submit, she will take everything she can from you. It's best to just walk away/ignore.
Although to be fair there is a practical argument for men and women keeping their last names separate. From a bureaucracy perspective its extra work as when it comes to official documents there is sometimes situations where you have to provide documentation regarding proof of name change etc. I have seen cases where to avoid this the woman and man both keep their surnames the same after marriage but the children take on the father's surname, which I think is reasonable.
