I hope so.

The article seems to be more about the logistics of how we can get to a point of handling smaller transactions. I agree it could be useful but we still have a long way to go.

“People need to be comfortable having a small stash of bitcoins. What this is kind of fits that mould,” he says of the Bitwasher project. “Everyone should walk around with 1-2 bitcoins that they can use for small transactions only. If enough people are doing that, then the volality of currency goes down and the value of the currency increases.”

I don't think he has thought through his own example. First, one or two BTC is about one or two hundred bucks in fiat at the moment, possibly much more in future - a lot of money for most people to walk around with for small transactions, especially from a global perspective. It's as though he imagines a BTC to be a physical coin worth about a dime or a quarter. Secondly, for his vision to be true some day - 21 million BTC would somehow have to be shared as walking-around money by some 7 billion people, giving each person about 0.007 BTC, I think, with none left over for other purposes.
Interesting concept, unfortunate example. Perhaps Satoshis would work out better.
