First off, Liechtenstein could easily continue to exist because of today's widespread philosophy of Westphalian sovereignty, that countries have a right to continue to exist. . . Secondly, even if Liechtenstein were absorbed into another country, it would probably at least try to keep the same sorts of laws in place.
A century from now, a lot of today's political makeshifts like "sovereignty," a human construct about as arbitrary as the rules for baseball, won't necessarily have the force they do now. And what would keep the Liechtensteiners from choosing to join up with a neighboring country and subordinating its laws to theirs?
The government claiming to be hostile to cryonics is not the same as the population being hostile to it.
The mob in Liechstenstein doesn't necessarily have a say in the matter. Liechtenstein, a country with a population about half the size of Prescott's here in Arizona, has a small, generationally perpetuated ruling class whom Bill Faloon apparently managed to alienate. I haven't seen evidence that he's thought through the implications of that yet. Why would the Reanimation Foundation want to stay in a country which opposed its entry from the very beginning?
By contrast, when Dave Pizer helped to negotiate Alcor's relocation from Riverside to Scottsdale, he got the relevant officials at Alcor's new home to make a show of welcome, whether they meant it or not.
