Could California succeed at banking where Wall Street fails?

This is the kind of thing that we could do before California gains independence from the United States:

If California had a bank controlled by the government rather than profit-hungry shareholders, public banking advocates argue, the state could fund social goods that often get the cold shoulder from commercial institutions: infrastructure projects, low-interest student loans and affordable housing. California’s treasurer and attorney general just published two studies that look at whether a state bank could help the newly legal weed industry by providing a safe repository for cash that major banks won’t accept.
