This is because there was (and is) way less gold than silver, so gold is way more valuable. As such, gold coins were only used to buy things like houses, horses, and suits of armour. Silver coins were much more practical; the linked article mentions that Ptolemaic Egypt had to export large quantities of grain to bring in enough silver to pay their army despite there being gold in Egypt.
But more than that, if there is a complete societal collapse, the metal you'll want is iron. Societal collapse doesn't mean things continue as they have been except there are no safety or food quality laws. It means everybody goes back to peasant agriculture using tools made of wood and iron (well, steel, which is iron with extra stuff in it). If money is used, it might well be something where no coins actually change hands; everybody just remembers how much they owe their neighbours, and how much their neighbours owe them. That, if course, assumes that in the event of complete societal collapse, we don't decide to give local communism a try.
That's a misconception. Most people in ancient and medieval times had reasonable access to clean water. They drank wine and beer because they wanted to get stoned.

It's actually standard practice for secret agents to use their real names, as accidentally failing to respond to a pseudonym is one if the easiest ways to blow their cover.
Furthermore, Bond is a secret agent. The fact that he's a spy who has tons if amazing adventures is not public knowledge, let alone well-known. We the audience know James Bond as a super-popular action hero from a long series of movies, but in his own universe there is nothing particularly special or noteworthy about the name James Bond.
Bad news for the Libertarians: silver was historically way more common for money than gold was, to the point that languages like Irish and French use the same word for money as for silver.
