Companies have protocols where you get an email and have to wait a few days before they send out large amount of money (and that setting can be modified by the user by the same way). I would maybe be comfortable with a 2-of-3 multisig between Switzerland, Singapore and US. I'm already trusting 3rd party to hold my private keys though: it's a 2-of-3 multisig between 3 bank trezors (the banks have no idea what I am storing though, they probably think that it's just gold). It would be easier for a bankrobber to get the gold from the other vaults than to rob multiple specific banks in multiple countries. Anyways you are right in that it's much better to require physical identification for retrieving large amount of money, and you get better privacy by the physical trezors.
