I don't understand why there's an expectation of altruism. If I can exploit your stupidity to take your money and make it mine, then I'm going to do it when it's legal. But, then again, I live under the notion that humans are innately selfish beings.
This guy probably knew what he was doing was illegal, but did it anyway because he figured it was legally gray enough to test the waters.
Anyway, "libertarian investors" and "unregulated environment" are euphemisms for free market, and in a free market the "weak" die off and the strong survive. It's Darwinism at its best, and I'm surprised more people aren't aware of this.
The whole reason you have to invest an abnormal amount of time and energy into securing your own bitcoins is because 1. Someone isn't doing it for you (who would normally be paid to do it, like a bank keeping your fiat safe), and 2. because if you don't, someone is going to steal that shit right out of your digital hands.
People are greedy and we shouldn't be surprised when we get confirmation of what I thought was an obvious fact of life; instead, we should simply design our systems with that as a priority in mind.
