Engineering might just play the key role of developing libertarian utopias - - home to maybe Peter Thiel and Ron Paul. Engineers designing and constructing self-ruling floating cities - - city/states on the ocean. The term is referred to as "Seasteading" - - think pontoon-type structures or giant barges (or think Waterworld without the gills). The technical challenges are daunting enough. Imagine the legal and accounting efforts to create independent, self-ruling tax havens in the middle of the Pacific Ocean.
