Patri Friedman is sick of the jokes about floating tax havens. About a decade ago, the former Google software engineer (and grandson of Nobel Prize-winning economist Milton Friedman) co-founded the Seasteading Institute, a nonprofit with the stated aim of developing a model for self-governing offshore communities. The idea was to allow people to set up more laissez-faire laws for themselves on mobile, artificial islands resting in international waters. An invaluable experiment, he calls it now. Also: "Baggage."

The institute's Silicon Valley backers most prominently included Peter Thiel, the conservative billionaire and future Trump adviser, and traded in no small part on Thiel's imprimatur. But the effort was as impractical as it sounds, and it drew criticism from local leaders and good-government groups as a form of neocolonialism. In 2018 locals defeated a commercial spinoff's attempt to establish a seastead off the coast of Tahiti. Seasteading, like vampirism, is now on the unofficial list of topics not to raise with Thiel, who hasn't written the institute a check in at least five years.
