I am ... confused by your statement.

To simulate a Godzilla incursion and check if the movie where Godzilla attacks San Francisco makes an accurate depiction of what would happen.

For science.

The real question is would a Godzilla incursion be good for property values (novelty, tourism attraction, remove some housing stock) or decimate them (safety concerns, change the spirit of neighborhoods).

Depends on the cost of Godzilla insurance, which currently is quite low. Lock in now!
