Australia keeps 25 million people alive in a first-world lifestyle. Bitcoin keeps computers warm.
No, Bitcoin creates more than just heat: it created thousands of jobs (see section "Bitcoin already benefits the economy" in http://blog.zorinaq.com/?e=82).
IOW if you think Bitcoin is not worth it, then Australia is not worth it :) Thanks for this interesting comparison!
