Your cestui que vie trust is your corporate identity; it holds title to assets in your estate, for your exclusive, beneficial use. Having a corporate identity is almost mandatory in the modern age (Treefarmer excepted). Most people have a DL, maybe a bank account, maybe a home mortgage; these are all contracts with a corporate agent. Since contracts must be between equals, you as a live human cannot contract with the bank. So the CQV trust is useful, but it is only for your beneficial use: whenever contracting with others through your trust would not be beneficial, such as for a traffic ticket, you the person, acting as administrator for the trust, refuse to contract. As shikamaru notes, most of the business you do is with public corporations, so you can/should use the trust for that, its main beneficial use.
