Yes, and you should read a little less Ayn Rand and broaden the thoughts you allow yourself to think =P.
For example, what did OP say that suggests they don't allow themselves to think broadly? It's a baseless assumption rooted in your own personal biases, and has nothing to do with the idea at hand.
Which is not to say that I'm particularly enthusiastic about sea-steading. Who's to say though, that its time won't come?
