I'm very happy that South Korea has taken these steps. That serves as a very clear indication that Seoul does not want Uber declaring their own law on the country.
Are you suggesting that we legalise everything that is currently illegal, so that we would have no need to prohibit anything and turn nobody into criminals?
We could very well apply this logic to say, murder. Why not let us legalise murder, set up appropriate channels for people to hire hitmen to kill each other, so that the underground killers would not have any more customers and then they will gradually die out?
