Whenever the government banned Bitcoin for and from any uses, i do believe the government are not capable to monitor each users/people who doing transaction with bitcoin, unless, they place logger/monitoring tools/apps for every ISP, monitor and track every ID's. traces every traffics and inspects every packet.
Bumping head to the wall is much easier than doing that!
Yep I agree, it's just too much work for them, they don't have the manpower or the time.
