New Angeles City Hall - Android Netrunner

I chose today's card to address an issue I have with some futuristic sci-fi works. Here's the card:

Home of NCIS: New Angeles.

Some card stuff first. It seems alright, though I'm confused how city hall helps runners avoid getting tagged, and why city hall is helping runners in the first place. Maybe the building or the sheer number of people in it help mask the runner's signal, but it would be nice if the card explained that instead of giving a generic quote from the city mayor.

But onto my main issue. Why do science fiction works, in order to make a futuristic sounding city, simply take an existing city and add the word "new" to it? Are city namers so creatively bankrupt and lazy that they constantly use this formula. New Who gave us New New York. We have New Gotham, from the short lived Birds of Prey live action series and I think from Batman Beyond. Yu-Gi-Oh 5Ds gave us New Domino City, and on and on. What is it about tacking the word "new" onto something that makes it more futuristic?

And, using this card as an example, what happened to the original city? What happened to Los Angeles? Was it destroyed? Was it rebuilt as New Angeles? Was New Angeles built over Los Angeles? If it was simply rebuilt, how much of Los Angeles was built over to justify the "new" status? People usually don't tack on a "New" every time their city suffers a major disaster and is rebuilt, else Nero would have dubbed Rome after the fire New Rome. Well, he still might have, but the name obviously didn't stick. Same thing with London and Chicago when they suffered disastrous fires. Why would it work in the future if it didn't work then?

My point goes to all sci-fi writers: Don't tack New onto a city for your futuristic city unless you have a really good reason or explanation for it. Otherwise it comes across as lazy, and I'm certain you can come up with better names for your cities.
