I understood that they want to profit. But people are stealing parts or painting over, so they either have to put security (50k per year) or sell it paying 200k for the removal. They really are asking potential buyers to pay the bill. For what I read about VARA, it applies only if you paid the artist to paint the graffiti, and later you decide to destroy it, as the artist keeps some rights even if you own the art.
