The EU is not most jurisdictions and have put pretty hard rules in place. What you are saying is that you think that it is OK for a lowly judge to force all companies that deal in personal data to choose to either operate in the EU or in the USA.
That is clearly not an optimal situation and will clearly have to be resolved, either by one side changing their rules or by a common agreement that voids GDPR for American courts.
This is not an optimal solution, which would be a negotiated agreement between the US and EU on how to reconcile the laws, but saying that doing what the court demands would put you in a hard spot of your own making isn't really a defense.
On the off chance an agreement is reached with the EU I fully expect that they will allow law enforcement access from both jurisdictions; None of the EU laws restrain law enforcement in this regard.
You can try and denigrate the judge all you want, but they have the authority to make these demands, and your only recourse is the supreme court or congress. Laws are a cost of doing business in the US.
That is clearly not an optimal situation and will clearly have to be resolved, either by one side changing their rules or by a common agreement that voids GDPR for American courts.
