You call it a "threat", but that's literally the whole point of Bitcoin. It cannot be censored that easily. It's a feature, not a bug.

Even if laundering is the whole point of bitcoin - a view I'm sympathetic to - it needs to be at least semi-legitimate for laundering to work. If market forces mean that the fraction of miners who are launderers increases over time, then eventually governments will consider it all tainted and it will no longer be useful for laundering.
