The article doesn't mentions that the judgment would force Steam to facilitate game resell though.

You can be allowed to do it, but it can still be a pain in the ass to do it (giving access to your account, etc...).

Same goes for a marketplace that would use that rule to allow people to rent the games. None of theses games has to facilitate the resale and they aren't forced to sell license to the marketplace either (though they could buy license through Steam or anything else, but that would still go with the "pain in the ass" argument).
