Yes, some trust will need a bank account. But, many don't or won't. Holding trusts usually has property income and bills handled by another trust. There is no need for a trust that owns a car, truck or house to have a bank account. Any person-entity may pay a bill for another, and no one should care about it.
Sovereignty means supremacy of authority to rule.
This is one of those double binds, a push-pull . Good and bad together. It is tough to decide. Certainly we don't want and an oppressive government that makes laws abridging our rights or legislating for small or large groups by penalizing others, but we should want and need protection. Oh, and by the way, because I feel sovereign, I want it all tax free, because I say so.
