The modern level of financial surveillance – KYC, etc – is only a few decades old, and collects more info for the state than any 'general warrant' could. Even in fairly-free countries, the burdens & murky liabilities created by turning every financial agent into a part-time police informer has the effect of persecuting & impoverishing disfavored individuals & groups – even those who've been convicted of no crime. In unfree states the same surveillance helps quash all kinds of dissent.
A blind faith in authorities' use of financial surveillance ignores history & the current reality of billions living under untrustworthy regimes. Many hardly even pretend to offer "rule of law & democracy".
