Even if there was no reserve requirements, or other regulation to limit money creation by banks, a regular bank still would not have powers similar to the central bank. Imagine a fraudulent banker who keeps adding billions to his own account. Suppose no-one notices. The banker starts to buy mansions and islands with this made-up money. Every time his bank transfers money to other banks (to buy those mansions), the bank loses some reserves. At some point the bank has no reserves left. Even if the reserve requirement was 0, having no reserves would mean that you could no longer transfer money to other banks.
