I joined here because I was doing research for a possible university paper that now might go into an other direction than bitcoins.
If it is for a university paper you will do well to bash the hell out of Bitcoin and highlight things such as "its creator is an unknown person!" and "a depreciating currency is bound to fail because nobody will spend".
You are well on your way with your response that old people should be taken care of by the state. Being a university paper I would also expand that to include minorities and the poor and lower middle class.
Here are some buzz words:
Keynes
ponzi scheme
bubble
unregulated
A+ for sure.
(I used to write outlandishly liberal papers for high grades to get through college myself, gotta look out for number 1)
