Fractional bitcoins work just fine (down to 1/100,000,000, per
https://en.bitcoin.it/wiki/Satoshi ).  If BTC goes to 100,000 USD we'll
just start pricing things in "thous" or "mils" or something similar.

In other words, there are already 12 quadrillion Satoshis in
circulation, plenty to absorb any further deflation.
