We (tech geeks) tend to think of situations like this as analogous to code, where the local declaration supercedes the global one. We see a specific investment platform with specific terms and rules and our gut says those override more general ideas about how it should work because they're more immediate to the context.
But civil society is the opposite: Contracts cannot violate the law; the law cannot violate the constitution. The justice system would care about the terms of the DAO only insofar as those terms fail to conflict with the law, which includes a massive body of precedent in contracts and torts.
