If bitcoin becomes a universal "store of wealth" it automatically becomes the only currency: most marketable, most liquid, cheapest to transport and store currency. See my big comment on how this happens elsewhere in the comments in this post. Gold is not currency because it's too damn expensive to store and move. Capital gains tax evasion - maybe, I'm not a lawyer and I'm not advocating it. But it's clearly a motivation for some people to spend bitcoins directly without going through an exchange.
