Though there are many problems of monitoring on Bitcoin, the root is to remove the centralized banks as entity. It is used widely as investment tool, or sometimes to hide the money of tax auditors, however, Bitcoin proclaim that its intention is to kick out the financial institution, and to purchase a car with a pocket cash to remove it.
I don't think bitcoin will remove the centralized banks and there will always be a need for them and their various services, but what bitcoin shows is its a viable and workable alternative. Bitcoin and the blockchain will undeniably influence society eventually but I don't think it will overthrow or drastically alter the banking system anytime soon.
