I worry about Prince Hans-Adam. I'm a big fan of Liechtenstein. But I worry about its stability in the next 5-10 years. Liechtenstein is a combination of a Monarchy and a Democracy. They have one of the purest democracies in the world. But because it is one of the most pure there is a large number of people who want to hit 100% and want there to be no monarch. But the liechtensteinian model will not work without it and without that veto power. Then it would be actual pure democracy and you wouldn't want to see it.
It would be nice if it could actually expand into Austria a little, and then have enough geography to split in two. Then you could test both models.
