Saylor is talking about government central banks, not private banks. From the greater context of Finney's work and his other views I believe he was talking about a free banking system. 

These two views look alike on the surface, but are diametrically opposed at their core.  

 Saylor is alive & speaking in today’s world. Hal was pontificating about a possible future. 
They are not as opposed as it seems. 
Saylor has to be careful with his words.
