Applying cold, emotionless logic, a woman changing her name when getting married is plain ridiculous!
My wife would have changed her driver’s license, passport, house title, credit cards, business cards, and the list could go into hundreds of places with the advent of the internet. I agreed with her, it was a stupid thing to do. We probably had a 15-second discussion about it.
In some other countries, you have two last names and they do not change. A child is born with the first part of father’s and mother’s last names.
Congratulation on your decision.
