The truth of this comment is heavily based on location. While true that there is no way to know how a government will act in the longterm, investment in land in a country that is receptive to your values and morals may be advisable. Its like having a stake in the development of that society.

I have my own eye on el salvador right now.

Also, the comment is very pessimistic. I still hope that there will be a societal change in the future, with a rejuvenation of libertarian principles . owning land and or a home in such a place may be a life saving measure for those escaping a bad situation.
