Libertarian cities?

While this is interesting, the problem that I have is: what guarantee do these places have that a future Honduran government won't renege on the agreement?

DISGUSTED by an increasingly invasive state, America’s most capable entrepreneurs retreat to Galt’s Gulch, a libertarian commune. That was the theme of Ayn Rand’s magnum opus, “Atlas Shrugged”, a sacred text for libertarians ever since it was published in 1957. Actually creating such an enclave has been the dream of many fans of small government (or of none at all). Several have had a try at it, but their efforts have always ended in disaster (see table).

Now, for the first time, libertarians have a real chance to implement their ideas. In addition to a big special development region, the Honduran government intends to approve two smaller zones. And two libertarian-leaning start-ups have already signed a preliminary memorandum of understanding with the Honduran government to develop them. . . .
