Hmm.. you make an interesting remark: my thought process includes the transition period in which a monetary currency is also at play. There is the weakness probably, because it becomes an arms race for being the one who can hoard the longest. However, with only Bitcoin in circulation -- or rather #Bitcoin as lead currency -- one would need to spend to get anything accomplished.
And quickly thinking ahead, this should hold even if on a local level any other coin or currency is applied, and Bitcoin is a global currency.
