Thinking about institutional needs it might depend on what is needed to be hidden to be able to operate as a business, assuming 'normal' rules of competition apply. However i wouldn't rule out a different way of doing business, for example on cooperative principles, in which transparency would be a key requirement. It might a question of what is required to be disclosed and why (e.g. for the public good). Is it conceivable that in future companies work alongside each other not in competition to maximise profit, power and influence but to act in the service of humanity? I think it is. How we would get there as a species is not clear however.
