Lavabit has revealed something incredibly important.<p>The US Government has no problem with seizing your <i>private keys</i>. It claims the right to impersonate you without your permission.<p>It no longer matters which system you use, Sovereign Keys, PGP web-of-trust, traditional PKI, they're all the same. Services based in the US can be MITM'd without leaving any traces.<p>If this is allowed to continue uncontested there will no be no way to stay secure online. The <i>only</i> solution is a partial solution, to create decentralized services. This, at least, will require the government to seize the private keys of each individual they want to track.
