It's very unfortunate that the legal system doesn't have a way of saying: this asset is mine and I'm handing it over to you for safekeeping, but it is still 100% mine which means it cannot be used to payoff creditors in any circumstance whatsoever and can only be returned to its rightful owner, meaning me. It may be fungible, so that it can be shuffled around with assets of other customers, but that doesn't change the fact that the quantity of units I deposited still belong 100% to me.
