If you do it that way you are importing a good.

The end of this would not be that Steam relenting enables folks to start using foreign currency to get cheap games on a publicly traded space.

What will happen if that goes through is a swift increase in taxation of export of digital goods. You’d have countries fighting tariff wars over video games.

The idea that you can use foreign safe spots to buy and sell goods at a cheaper cost is something that only rich people get to do. As soon as it becomes broadly available to the general populace the governments crack down on it quickly.

Discrimination only applies if the two parties are similar. In this case the location makes these parties dissimilar due to the inability to just go from one place to the other legally. Brazil gross national income is 1/3rd the US. It makes sense to price things at 1/3rd the US price.

Steam taking 30% is a better deal than any other form of media gets by a mile. It’s crazy folks complain when it is so easy to self distribute a video game, people have been doing it for years and years. Steam doesn’t even require you to sign up for exclusivity like basically every other distribution/marketing service does for all media including other video game services.
