That's an idiotic statement. What if the cost (in terms of money or moral hazzard) of dealing with abusers is less than trying to prevent abuse?
First, please learn how to properly format post if you intent to quote people on /. It uses standard html which any idiot can pick up. Use of the quote tags would be very helpful.
I thought by now it would be obvious to even idiots why a currency, even bitcoins, must have some form of regulation in place. Obviously I was wrong. Here I will explain it to you in a simple concept, I will try not to use big words, but if one confuses you I'm sure someone can explain it to you in small terms.
Regulation will help prevent abuse and will provide some form of protection from the events that happened at Mt Gox. You see, if Mt. Gox had been regulated like a bank when this thief happened then the users could have had some kind of insurance in place.
In other words while the theft still could have occurred, the users wouldn't be out all of their money. As it stands all the users of Mt. Gox are pretty much screwed. With out regulation they have no legal recourse.
Regulation would also help prevent the current freefall that bitcoin values are taking now. With proper regulation and insurance the closing of the Mt. Gox would have had barely, if any, real impact on the value.
So here is the deal. For any currency system to be successful in the long run it has to have something backing it. That can be a physical object such as gold or a the rule of law.
So again, regulation is a must and not an option.
