Problematic!
Your net worth could double or better while on vacation indeed sitting at an airport! How accurate is this ever going to be. Not very, and what about social freedoms? Incredibly intrusive on your civil rights. Ordinarily your net worth is of no use to border agents so why this information is suddenly up for grabs from everyone in realtime staggers the imagination. I don't see how this is ever going to fly. Beuraucratic mismanagement, the public won't tolerate this over reaction from government for a second.
