Today, your business is minded by the government and large corporations. As a result, the rules that they want enforced are the ones that actually get enforced. Anonymous money is why you have no ability to prevent people from buying your government: no one with the power to mind people's business actually wants to enforce such a rule. If you give everyone the power to mind people's business, then rules that the people want enforced can actually be enforced.
There is no way to regain the ability to sanction bad behavior unless you can mind other people's business. Financial privacy feels nice, but it gives the wealthy the ability to rule over us with little recourse. Are the benefits worth the cost?
