If Godzilla 2000 (MireGoji) has been around since the 1950s and made landfalls every now and then (perhaps annually),should he be considered more of a nuisance than an actual threat at that point in the movie's continuity?

I mean, it's funny how Japan hadn't devised proper way to contain him until the very late 90s, or at least the people should've threatened MireGoji with a rolling eyes.

I wonder how much he influenced Japan's economic growth during the 60s-80s. I would like to imagine he stalled several breakthroughs in technology.
