> there is no real-time dependency on online systems for use of physical currency You are underestimating degree of our reliance on banking. Stores, restaurants and repair shops don't have enormous vaults with cash — they store money in bank accounts. If banks make cash transactions infeasible, businesses will suck it up. If your local coffee shop stops accepting cash, you will have to find another one, possibly located in different district (or even different country...). Many countries enforce mandatory use of bank accounts for business — companies are literally not allowed to operate in pure cash. When banks conspire to make cash undesirable (via high cash collector fees, shunning low-denomination bills etc.), local entrepreneurs begin go "cashless", a trend already seen in many places. Never mind that, ­— even if your local legislators force shops to accept bills, who cares about them? Brick and mortar stores are deteriorating all around the world. A lot of things already can't be bought offline, unless you take an international flight each time you want to purchase. When your local electrical parts shop closes down, will you open your own? Or just order parts online and pay with VISA like everyone already does? In not-so-distant future you will be able to spend your cash on bread and not much else. Until the backer becomes unable to spend his.
