Call me crazy but if I am ever in a position to transfer $150M I'd probably also want a third party involved to make sure the transaction goes smoothly, like a bank. Like we do today. With wire transfers.
If you meant in terms of escrowing to make sure one party doesn't back out, then I agree that comparison wouldn't apply.

Sorry about the fencepost error. (Perhaps I was originally intending to say "inflationary finance"?)
Whether it is in bitcoin, CHF, EUR, USD, gold, platinum, Amazon Coins, Zorkmids, yams or sheep skins, insuring a transaction will depend on those factors.
In the meantime, the $150 million is in limbo.
