the arguments against hoarding at the time went like this.  "unless Bitcoiners spend their money, there is no way the merchant economy can get off the ground".  this is so wrong on so many levels.  sometimes ppl just need to save money for rainier days.  it depends on their age in life.  savings can be used to lend to promising Bitcoin projects.  it also creates scarcity during this inflationary phase of reward issuance which helps support the price. point being, there will always be hoarders.  AND, there will always be spenders.  so my argument was just "STFU about hoarders. please".
