What you said has no relevance to the original topic. Doctors modifying their payment structure is not at all the same thing as leaving the country. And an argument by analogy only works if the analogy is a strong one. This particular analogy is weak because the author failed to distinguish between personal property and the public economy. Considering that the author is arguing in favor of a libertarian candidate, and the concept of personal property is a core tenet of libertarianism, the author has shown that not only was the analogy doomed to fail, but also that he doesn't even understand his own candidate's political ideology. It is simply a smear of Bernie Sanders by way of ad hominem.
