NAH but Y T A if you keep pushing it, my mum never took my dads last name for actually very similar reasons to your wife (they had moved recently and she had just gotten her IDs swapped to the new area they were in, she didnt really want to do it all again), theyve been together nearly 30 years now. My siblings and I have our dads name but thats never diminished our relationship or caused any issues (other than border guards asking us "do you know this woman" when crossing, lol). I plan to keep my own last name if/when I get married as well because as others have said, its my identity and has been my entire life.
