You launder the money by inconspicuously inserting into legitimate accounting. The whole point is that you’re trying to avoid attention. The taxes are an unfortunate side effect.

An auction that makes the news is nothing if not conspicuous. It’s tantamount to lighting a sign and saying “follow the money trail starting here”

I don't think that's the point in GP's post. I think GP means they stage a big "sale" and make headlines, so people start looking for mint condition N64 games, already primed to think of them in terms of millions instead of thousands of dollars. Conveniently, they would have bought up all of the rare games before this.
