Yes, somewhere you are right. But I think this problem we will always have: Times are changing and even a royal house like the Habsburgs must find a way between the historicial connected background, the tradition and modernism, which I also think so, is not too easy. Surely Otto was the last one, who himself lived at the time, when the reign of the Habsburgs was still alive, and all his descendants cannot share this. But that's like it is. There will always be the historical background, but times are new.
I hope the house will find a way to deal with this change, but sometimes even in royal families, changes are necessary and cannot be thought away, when times are moving. I really hope, Archduke will make the best out of it also by finding that way in between.
