I've had the misfortune of being in banking much of my life and met many POS rich people that do this kind of stuff. Trust's most certainly can be used to hide your identity. Banks are more than willing to let rich people leave their names in the bank trust as a service to hide their identity. Trusts are not used as a financing product, they are a wealth management tool.
I'll give you a challenge. Find another vehicle title that has "trust" on it other than a yacht or private jet. Time saver, you won't.
It's to hide the owners identity. I don't know why people are arguing with me about this. Trust's are a wealth management tool that provide a number of services including hiding a persons identity.
