;I would disagree with the notion of letting people exclusively guard their own keys. Trust should be distributed between various parties, in order for this industry to gain the consumers’ trust. When it comes to FIAT money, we all share safe-guarding responsibilities with at least one more party. At the least, it’s the bank. At the most, these are additional people that must sign each transaction. How this trust would be distributed? There are various methods. Technology is not a blocker in this case.
