It's my understanding that there was an alternative asset currency movement that favored adopting a monetary system similar to what existed in Canada at the time. One of the reasons the Federal Reserve got any momentum at all was because the US monetary system at the time was vulnerable to wild swings in interest rates as the result of peculiarities in how the banking system was set up. During harvest times, interest rates would spike, and then plummet during summer and winter.
Canada lacked this symptom of an unhealthy monetary system.
I wish I knew more about the personalities involved and could then give you a better answer when it comes to a PoD, but I, unfortunately, don't.
How our monetary system turns out afterwards depends on which one is adopted. Regardless, something needed to and eventually would have been done about the flaws of the National Banking System. There were a ton of ideas floating around on how to deal with the monetary shenanigans in the US around the turn of the century, some more and some less likely to be adopted.
