Your mistaken as to why they have not issued higher denominations. They (the government, police, reserve banks etc) want to restrict cash transactions and get all transactions recorded. Not just to control narcodollars or terrorist fundings (the excuses they give) but also to crack down on black markets, cash payments, tax avoidance and libertarian types. If they can see it they can tax or confiscate it and its easier to seize funds in an electronic account than wads of cash hidden away by the populace
And its fiat money so its not even a promise of money (that promise of money ceased to be printed on Australian banknotes around 1931 but that promise had ceased to be honoured in 1915. Look at the early 10 shilling notes and their promise to pay the bearer on demand a half sovereign).
