How could you be so sure?
For the same reason you seem bent on ignoring the Romanian Royal Family after the King passes away, I would guess. The 1923-constitution is gone. It will never be revived, no constitution ever is. In 2009 Prince Karl said so himself. 'My family has no claims to, and will never claim, the Romanian throne'. If and when Romania is to become a monarchy again, it will be under a modern constitution, with equal primogeniture and a connection with the past monarchy, through its leader. The EU, the press, the population in general and women specifically will never allow otherwise, and the cost to the government will be too high in negative publicity.
Restoring a monarchy is not about the personal preferences of each individual who happens to write and talk about the issue. It's about realizing what can realistically be done, how can the process be taken forward and how can people be convinced. The way to do that is through tradition, continuation and emotion.
The Romanian Royal Family are the ones representing the monarchy in Romania. They have been since the 19th century. There is no role in the future of a Romanian kingdom for a foreign Princely family with no connection to, or interest in, a modern throne, and it is unhelpful to seek to undermine the RF, when the goal is to restore a throne.
Many on these forums have asked whether or not the Romanian Royal Family wants to see the throne restored. I would say that their work around the country, trying their best to play the parts they can in civic and social life, proves that they do, much more so than any German Royal or Princely house, who regularly dismiss in interviews, returning to the monarchy and being quite content with their lives.
When it comes to the members of the RRF, and how they sometimes seem to disagree on matters, I will only say that I have fewer siblings and more disagreements in my family, and we're not the ones trying to navigate a post-communist era in a country we weren't allowed to be born in or grow up in, where people don't really know us well and where the establishment and the media doesn't know exactly what to make of us.
I genuinely see them trying their best, and I wish that sometimes would be more appreciated and understood.
