Pokemon doesn’t have direct control of the mechanical system by which pokemon cards are traded. They also don’t get a percentage cut whenever a pokemon card is bought/sold on their storefront, and they don’t take pokemon cards as payment for games, software, and computer hardware. Valve facilitates, profits from, controls, and could ultimately shut down, these online casino spaces. They actively choose not to, and participate in using loopholes (see the xray scanner). Ideally, yes, the government fixes this. Realistically, any solution that isn’t going to take years, and be easily bypassed with a VPN, or just having your company be based in a “sanctuary” country, is going to lie with Valve. Either self enforced or forced by the US govt, they have the means to kill gambling easily because they control the accounts involved, the systems used to trade said items, and the virtual currency players earn. Even something as simple as adding age verification would help. They don’t have to stop, just accept responsibility for having an in game slot machine that spits out items that have real world value, and follow laws and measures to protect minors.

So yes. i hold Valve, a massively profitable company directly facilitating and profiting from its illegal gambling industry to the point where the casinos openly sponsor pro teams to a higher standard than the company that prints pokemon cards, which can be bought and sold and gambled with like any physical good in a physical game of chance.
