I’m not sure if this is just what you get from an unregulated industry when money is involved or the people interested enough in BTC are too inexperienced to do it right.
I think it’s what happens when you treat a decentralised currency as if
it were centralised. Centralised currencies must be regulated to prevent
these things from happening and to give people recourse when they do.

In general, bank accounts are eventually consistent, but this works really because the bank can leverage laws to extract payment from costumers. Interesting subtlety!
