I see what you mean, but I stand by this. The main point is that in this decade this sort of thing is not insurmountable or as much work as it once was for some of us.
I speak mainly from the perspective of someone in the Philippines trying to get stuff that's exclusive to US Target, Walmart, or TRU (only the last has a presence here, and even then it's just as a brand one of the major malls uses for their toy stores). I don't know if this, and "importing from Japan to I assume the US via online storefronts", are even really comparable experiences.
For one thing, here we were almost entirely brick-and-mortar, and of late have been sliding back into that for some reason. Then and now, the local distributor mostly got mainline waves, although they did manage to invest in bringing in more exclusives when the live-action movies and Universe 2.0 were white-hot (and we similarly ate good when Combiner Wars was hitting). But there's a lot of stuff that's missed, and store exclusives are always wait-and-see, then and now. And that was by and large the main source for anything; the only real alternatives were maybe 5 reputable specialty store brands.
Online shopping wasn't much of a thing here until the late 2010s, and it wasn't until the pandemic that it became normalized/commonplace. Online storefronts, Amazon shipping to here, and so on. The government (and/or more likely mid-level functionaries wanting to make an extra buck) always wanting to have fingers in pies and magically compute a tax on whatever also complicated importation and such, making it unfeasible sometimes to do much other than just hope stuff would be imported officially.
These days the distributor still has to play it safe (and they've opted out of some product), but there are many more local players in the specialty store space (with online presences too). There's also international storefronts that are more accessible locally via online shopping, although iirc one still can't shop on Target or Walmart's websites (the latter used to not be the case) without a US address. But there's also Hasbro Pulse, which does offer partner exclusives, which is kinda neat.
My point was that it's generally easier now, which I think holds true even if it were easy then. In either case, the whining and resorting to hyperbole like "corner store in Botswana exclusives" is out of place.
