Some guys on this forum keep saying that we urgently need people to sell goods/services in Bitcoins, preferably never exchange them to fiat throughout the production process. It's definitely good for the Bitcoin economy if finally many merchants are willing to do that.
While I agree with what you write. Balance is good. There seems to be a current lack of balance. It also appears that imbalance is growing. It is a really simple ratio to visualize.
Goods traded for Bitcoins

Currencies traded for Bitcoins
As this ratio tends toward infinity, Bitcoin tends toward world domination.
As this ratio tends toward zero, Bitcoin tends toward a Ponzi scheme.
The big damper on Bitcoin adoption is that most non-bitcoin users understand the above intuitively. What they perceive is the above ration is tending toward zero. A predominance of speculation talk only reinforces that perception.
