Of course you have to have a dairy license. That's the government's way of being able to stop you if you decide to be a felon and/or cause problems for the community. You have to have a license to prove you are legitimate and it is one notch of insurance that you're willing to be held accountable for your actions in the business. (The license fees stem from costs to keep records and pay salaries, nobody is going to do the job for free)
You saw what happened with Mybitcoin right? The community had trust and trust alone to use his services and they got smacked in their face. Now, had he had a business license, we'd know exactly where to find him and have a lot more leverage over him as a community.
This is the perfect example of the level at which we have arived. People actually trusted a nobody with huge quantities of money! We are so used to live in this world where theft is either regulated and indoctrinated as normal and any competition in the scam sector is prosecuted, that a lot of us dont know how to take the minimum precautions.
In this sense I think Bitcoin is great because it will teach us a couple of lessons that we desperately need.
Well said, Hugo.
And the guy you quoted completely misunderstands what regulations are for. Regulations (even the good, voluntary ones) are not there to make people "reachable" and to make they responsible for their actions. There's no need of regulations for that, you don't need a "license" to be accountable, nor to abide your processes to arbitrary rules. Your customers just need a way to track you down if they feel you might harm them.
Quoted guy, trust me, state regulations exist only to protect established industries and lobbyists, and not only are unnecessary, they are economically harmful and ethically criminal.
