I like the takeaways, though I'd also add an additional one, that you should use systems that have reversible transactions. That way, when you fall victim to fraud, you can use the court system to recover your losses.
This is just saying “that’s what you get for playing with crypto you degenerate”. The fact is wires can also be irreversible and you cannot use the court system as a blunt instrument outside your jurisdiction. The value transmission medium isn’t the problem here.
No, it isn't. It's a reminder that we have all of this financial structure for a reason. The person you're responding to didn't make any light of the potential victim or call them a degenerate.
In traditional finance, you (Joe Shmoe) can't just wire someone ~100M USD, regardless of jurisdiction. There are controls, most of which have been written in blood or tears. Cryptocurrencies will also grow those controls, and we will all rightly question its value when it inevitably does.
