A central bank with a goal to serve Americans would be a great institution.
Who controls healthcare policy? Congress. Who controls food supplements? Congress. Who controls the minimum federal wage? Congress. Who controls taxes (both rates and incentives)? Congress. Entitlements? Congress. If you want better governance, vote for competent representatives, although I understand this is out of the hands of most and we’re being held back by the emotional and unsophisticated who vote against their own interests (broad strokes, lots of nuance and caveats).
The Fed could’ve even offered FedAccounts, free demand deposit accounts at the Fed to eliminate the unbanked and apply downward pressure to fees at commercial banks. But a certain party recently passed legislation to prevent that. Hard to avoid politics when they are driving suboptimal outcomes at scale.

Unless everyone wants to take their deposits out at once and buy treasuries instead!
It's very reasonable to criticise commercial banking for delivering such poor value to depositors that narrow banking looks like a better option, but regardless, if that's the situation, your choice is between suppressing narrow banking and allowing the collapse of the entire system. You cannot reasonably expect an institution like the Reserve to make the other choice there.
Unfortunately for those folks, Bitcoin is a weak vessel, and cannot, in reality, meet all the requirements. It takes tons of compute to create a Bitcoin, much less to process a transaction 'on the block chain'. It's not as anonymous as claimed, either, and should it be a currency, it's deflationary. Not all the implications of this are accounted for in the common knowledge about Bitcoin.
