He (the author) proposed in a comment on his own article exactly how he would eliminate "the" Bitcoin:
"Richard Murphy says:
January 21 2014 at 9:47 am
a) You tax it as a voucher
b) You make it illegal to trade in it
c) You penalise those who accept it
It does not stop the trade entirely
It goes a long way to doing so"
To paraphrase - he wants to use the bully power of government to stamp out voluntary exchanges between random individuals.
Subtle, he's not.
Edit: Woot! I just noticed he's got a self-promoting ad next to that very comment - an ad for his new book - wait for it
"The Courageous State
My new book, out now"
I am literally choking with laughter - off to get a glass of water.
