Not gonna lie, this position baffles me. Outside the rare stuff like SDCC Only pops, generally all variants are accessible in some capacity. The only one in recent memory I couldn't get was the Idol Indy. Sure there have been some hiccups like the Toy Tokyo debacle, which in my opinion is inexcusable for this marketing, but otherwise? You really can hunt down most of them for retail, provided you're ahead of the game and know when and where things go up and when to preorder.
Perhaps in the US however some of these exclusives are much harder to find in other countries that don't have the stores that they are exclusive to. Many of them are released as commons outside of the US, though not all of them. Many Walmart exclusives don't get released in other countries. The Black Friday mystery boxes weren't released outside of the US or Canada.
