Boosterpacks exist and print money which is why video games started using the same system, just replaced foil rarities with skins. Even digital card games still use booster packs when they could have stopped due to not having to physically print cards. Then giants like fortnite picked up the same system AND introduced a rotating shop on top of that so “booster packs” have even more incentive to be bought due to being time-limited.
Microtransactions aren’t going anywhere.
