Don't forget scammers thrive in this kind of environment.
Even without government, there is the majority of people... Scammers would be dealt with.
How so? Look at how badly bitcoin has dealt with scammers. A lot of people who were once Anarchists or sympathetic to the cause are no longer after seeing the reality of bitcoin.
People make mistakes. And then people learn.
Look at all the threads here in the Marketplace. People don't get scammed as easy as they used to.
There's a saying: "If you burn yourself with hot water, you'll be careful with the cold water too."
despite that, there is still a large market for scammers, as every day there are more and more bitcoin adopters.
