The cost would have been a lot higher. Either you have to reduce the dollar value for each recipient to keep the total amount the same, or, more likely, keep the dollar value the same for each recipient, “create” more money overall, and spike inflation significantly worse than it already has been.
You can’t just put so much money into circulation like that at once. The amount we already put in for covid relief is a big contributor to the inflation we have seen over the past few years. It devalues savings like mad, hurting tons of middle and retirement age people who have to live off of those savings for the rest of their lives.

Imo Genshin is a decent game at its core. The problem is that the gacha elements make it really hard to enjoy.
