That's not the question here—those $20 bills would still be "tainted". Moreover, the bar to demonstrate that they are tainted is reasonably low, significantly easier than getting a conviction. In this case, though, the persecution agrees that the assets are unrelated. As far as the courts are concerned, that's an established fact.

It's more like if you steal some apples, perhaps eat some of them and then the government freezes your bananas which you got through completely legitimate means unrelated to your (alleged) crime.

In the larger scope they are related if they can be converted back to cash. I imagine if assets are family photos or other maybe important items which have no value. But if they have monetary value I can see govt's position in freezing access to them.
