Although effective, this particular technique does not scale very well. Even if the UK had 100,000 kidnapping wrench torturers, it would take ~2 years for them to get through to pulling everyone in the UK’s teeth.
Fortunately for those who like laws having an effect, that's not factoring in the deterrence aspect of the first (few) toothpull event(s)
It's the law that's the issue. Avoiding enforcement only works until people actually care to start enforcing. There's also enough examples in history of people taking matters into their own hands if they disagree with something, doubly so if there's a law against it or something else makes them feel righteous. If you do bad in the eyes of the public (or its prosecutor), good luck swimming against the tide
