In games with loot boxes, on the other hand, many people end up spending totally crazy amounts for their income and essentially ruin their life.
It's true that there is a continuous scale between baseball cards and the casino, with several factors influencing the level of addictiveness (immediacy, amount of maximum reward, etc.) and it's not obvious where one should set the limit. But there should be a limit, and IMO it should be one that heavily regulates loot boxes (and in particular, forbids minors from buying them) and doesn't touch CCGs or baseball cards. Claiming that we should not touch loot boxes because CCGs are similar would be a textbook example of the continuum fallacy.
