If we've learned anything from the last year, any such adult won't be listened to. Trump's a bully, he feels that America should use whatever hard power it has to enforce its interest and damn the soft power or the 2nd order effects that the "adults" care about. He also feels that Europe is or should be America's vassal, and is annoyed that they don't go along with his every whim. Seizing gold reserves would likely be an easy way to bring an uppity vassal to heel in his mind.

The long term ramifications won't even be considered.
