Imagine how much sense it would make if you switched the gold bullion in there for Trezors, USB pendrives or anything that could contain bitcoins, and said Bitcoin wallets wouldn't be encrypted with a password at all! How safe would you feel about your investment?

That is exactly what i see there. Some guy which you are supposed to trust to hold your gold for you. And then when you need to move your wealth, you will need to hope that the guy driving the truck/ship/plane doesn't pull a heist on you and runs with the money.

Why bother with this risk when you can just hold it in bitcoins? I would like a reasonable goldbug argument for this very obvious point for once. I haven't seen anything convincing thus far.
