2) The relevance of the news and the ramifications on the psyche of a poor new investor, who possibly is looking forward to break the shackles of the conventional Banking system.

There's a chance that the crypto ban is an attempt to keep capital inside south korea's borders. China's ban may have been motivated by the same reasons. Its possible the proposed ban has nothing to do with crypto and is merely their states attempt to keep investment money inside their borders, rather than have that funding withdrawn and taken into other countries, which has spelled doom for asian economies in the past.
I like your point on #2. The plight of the poor investor is one well worth considering. It is known that china's 1 child per couple policy only pertains to the poor. The wealthy can have as much children as they like. The same might be said about crypto currency fines and bans. They only apply to the poor. The wealthy likely have ways of getting around them. Your point about "breaking the shackles of the conventional banking system" could be quite relevent here.
