That would only work if one of the end points are compromised, so by leaving out a third party CA you decrease the sensitive points from three to two. It of course requires the end point owners to have a correct key handling and key exchange, but that is no different from having a CA.

The only time a CA is useful is if the two communicating parts don't know each other, but in the matter of a bank the person is already a customer and therefore a key exchange can be done at a bank office.

I saw those as a wrap-up, not necessarily a cash-in.

They are still good to read. Especially the unforseen result of the laws of robotics causing alien worlds to be eradicated because the inhabitants weren't human. What if aliens have the same approach? Humans are then seen as beings of lesser value.

I would say that it is also a study on behavior patterns applicable to humans. When exposed to the unknown panic can occur.

Nightfall is a typical Science Fiction story that reflects sociology in a fictional setting - which means that the reader will have less prejudice of what's right and what's wrong.

No, but the CA can provide a certificate suitable for a man in the middle attack that is masking itself as the real server if the CA is compromised.

That's the weakness with the existing system of public certificate authorities. There are three points that can be compromised instead of two as soon as you have a public CA signing the certificates.
