I'm interested in which TLDs and server hosting locales would be best bets for protecting against gov sponsored asset seizures. I would like an EU country to step up to the plate as saying "If the U.S. wants a server taken down or a domain revoked, they have to go through our courts...We will provide fairness and due process to the accused". This may be boom times for migrating to non-.com domains.

What does it take to move to Europe and join a tech-based company there..?

temporary move or permanent? If you find a company interested in hiring you, it should be easy to get a working visa. A permanent move may be more difficult.
