A distributed currency requires a consensus as to who owns what coins.

I transferred a few cents worth of bitcoins between one identity and 
another.  It took a very long time for the first confirmations to come 
in.  After a few days, there were a couple of hundred confirmations - a 
consensus so large as to be entirely irreversible.

But a couple of hundred confirmations is a significant communication 
overhead, and has an impact on privacy.
