I don't follow.
You initially said whales who buy tons of games, I assume you mean individuals with 1000+ games on their steam account, buys all the dlc and mtx and loot crates, that kind of whale.
Now you are reffering to... the US government as a whale?
What are you suggesting... be done?
... and by whom?
Are you suggesting Valve functionally commit hara-kiri by ... some kind of intentionally angering the fascist government?
What are you suggesting, that Valve fund investigators to link Steam accounts to other platforms and websites, and then... report that knowledge to... the government?
They wouldn't do anything other than sue Valve out of existence for being antifa.
Valve cannot like... arrest people, issue themselves search warrants, ... and if they did set up a system to do something like this, kablamo, now it is instantly turned around to hunt down trans people after Valve is sued into a government buy out or being purchased by fucking Larry Ellison.
Please, explain to me what you are trying to suggest, I don't get it.
