The thing is that it won't save him from the current inquiry. Once the EU rules that he is in breach of the current legislation (which he clearly is) he owes them a shitload of money. Sure, he chose to not pay(he is mad enough to try). But that would later on make the Twitter penalties his personal problem.

And that is painful even for a billionaire. No more skiing in the Swiss Alps, no more Saint Tropez in the summer, no Monaco. And none of his assets can ever return to the EU or EU friendly allies.

That would probably make him even more mad.

Which I like. A lot.
