how do you prove to the bank the non-existence of a clause that would void the trust if this is done(and noticed)?

the main point I tried to make above was this: in normal life there is the "human factor"; like, if you look at a situation, you can reasonably comment on whether it's a positive situation from an actor's perspective; whether the actors were engaging in fraudulent activity etc. In digital-only world, there is no such thing as "probable cause", "reasonable doubt" etc.

which makes the application of smart contracts to real life intractable(IMHO borderline impossible for complex situations for the near future[~10 years?]).
