I've read it to learn about the history of money, soft money, hard money ,etc. I wouldn't say it's a good book because it literally says the same thing over and over again non stop, but it may be worth reading to learn about money. I would never re-read it though.

There’s no going back after reading that book. Free your mind!

I haven't read it.

Can someone explain the benefit of reading it for someone who is already orange pilled and familiar with Austrian econ?

No, I read this first:

There are some absolute howlers. This, for example:

There is no better evidence for this than the fact that the rarest metal in the crust of the earth, gold, has been mined for thousands of years and continues to be mined in increasing quantities as technology advances over time, as shown in Chapter 3. If annual production of the rarest metal in the earth's crust goes up every year, then it makes no sense to talk of any natural element as being limited in its quantity in any practical sense.

Gold is not the rarest metal in the crust of the earth. It's rare, yes. But other metals, such as platinum and iridium, are rarer.
