What about the lack of privacy in Bitcoin? Couldn't that be used to regulate the decentralized agents? http://www.pds.ewi.tudelft.nl/~victor/bitcoin.html
It's easily to be arbitrarily anonymous with something like bitcoin. The only way the government could maintain attributability for bitcoin accounts would be to put in place extremely aggressive enforcement policies that (hopefully) would not be viable.
https://bitcoin.org/en/you-need-to-know says "Bitcoin is not anonymous .. Some effort is required to protect your privacy with Bitcoin. All Bitcoin transactions are stored publicly and permanently on the network, which means anyone can see the balance and transactions of any Bitcoin address. However, the identity of the user behind an address remains unknown until information is revealed during a purchase or in other circumstances. This is one reason why Bitcoin addresses should only be used once."
