I don't like governments because they are a small group of corrupt, ambitious and evil people, but we have to look at things from another angle:
Who will ensure that scammers are punished?
Who will ensure that scammers will not steal?
How many cases of exchanges that have blocked people's accounts for no justifiable reason exist?
How many cases of ICO scam are there?
How can we accept that an anonymous exchange owner take our documents: (our passports, our income statement and our proof of residence)?
Even if we don't like governments, but we have to admit that we need governments to regulate this crypto market.
What the US government wants is to "protect its citizens"
