...because TPCi prefers money: If this was released in America, less packs will likely be bought after, dampening demand for more packs for collectors, among other effects that will bring less, rather than more, money in the long-term for TPCi...
On the other hand, Acro Bike and Magcargo(CST) is now a combo that could dethrone the need for Lele-GX in future, and sure, it's a shame that Magcargo is Stage 1, but no worries... Just wait until Lost Thunder comes out, then remember Ho-Oh-GX's GX move to bring out the Magcargo-GXes w/o going through the Slugma stage, and leave the slugmas to evolve into Magcargo from Celestial Storm, so that they can do their work by using their abilities to fish out energies for Magcargo-GX after said GX pops out from the Eternal Flame-GX move.. As for the Acro Bike, Smooth Over could downgrade Lele's current staple status to a "if you wish" status. Lele can't get you a card that's not a supporter like Magcargo + Acro Bike can...
^ But as of now, that deal could at least provide the buyer with all those special energy cards, as well as maybe easy collector-worthy cards w/o the need to pull them from packs, or paying extra money. I say, I wish I lived there, and understood their language w/o my brain hurting trying to understand what a set of Japanese kanji meant... But sadly, I don't live in Japan.
