Are you blaming government intervention also for inputs.io, labcoin, pirateat40, and countless other scams?
ITs been crystal clear from day 1 that these bitcoin security issuers and exchanges are violating relevant laws in just about any country on earth.

Now you may object to laws that require security issuers to register their shares, make certain disclosures etc, you may think its a good idea that an anonymous entity operating from a phone-boot in Nigeria can legally operate a money exchange and hold millions of dollars of other people's coins with no verification, oversight or accountability, but then you should protest those laws instead of blaming government for enforcing them when someone knowingly violates them.

Personally, I think bitcoin asset market is doing a very good job proving why there is a need for at least some sensible regulation and oversight, just leaving it up to the free market makes it a paradise for scammers and a useless minefield for investors.
