1. Agree the banking system acts out badly and has been responsible for bad things. However, the cryptocurrency market is basically no comparison into how many crimes are committed unfettered there. It is basically ponzi schemes running wild. I'm blown away by the amount of criminality, the psychopaths running riot without retribution. It's quite frankly insane how we get another news story almost daily about a new crypto scam being unveiled. Regulations will only stifle this core use-case of cryptos (scams) and therefore make it unattractive to conduct.
2. Yes however none of this in insured, unlike a bank. We are pretty much slowly trending in that direction but with a poor technology tapered onto it. At which point it provides no value whatsoever as a medium for a scam exchange fizzles out.
3 + 4. This can be done already, we have barcodes, receipts, validity schemes utilised by these companies that don't involve a crappy technology in between it... Again its basically a fancy word placed over something that has one use case: "to swindle you out of your money".
