It seems most of the answers and discussion here revolve around "smuggling" good which are available in both countries. What about goods which are only available in the country of origin? For example, there's a lot of Godzilla and other niche toys only available in Asia which I would love to add to my collection. I don't see why these toys aren't available in the US besides the market size.

I don't see why Backpack would be a "smuggling ring" at that point.
