Wallet encryption only goes so far.
For a start it's probably in main memory when the program is running, secondly you need to put the key in every time you start the bitcoind, how many lazy admins put the key in the startup script?
this violates us laws and international treaties on currency controls. It's conspiracy to commit counterfeitng and inciting others to commit wire fraud
Remember they used to hang people over this. Newton watched with glee as coin shavers he had caught were executed.
I found this fascinating and a alternative view to my own held beliefs on alcohol.
This really seems to be a better way at addressing social policy - yes beyond the genetic disposition to alcoholism there is definitely a cultural molding that determines behavior.
If the expectation of behavior (say from holywood and tvland) is a major factor in the behavior of those under the influence rather than say the quantity or concentration of ethanol, maybe humanity can address this by how popular culture programs us?
