Is it possible that if a user has enabled the recovery feature, and has his/her data held by a third party, then it's probable that a government entity could issue a written order telling the third party to give them access to then user's coins/savings?
Yes, absolutely.
The question is now which government will get to your coins first

But that's not even my biggest concern: what are the odds 2 out of 3 "seed storage facilities" will get hacked, leak data, or have an inside job rob users? If this takes off, there are billions of dollars worth of crypto to steal.
