The strength of something like this becomes evident in the optimistic future when governments (or at least accountants) decide to help opted-in users to report their taxes from Bitcoin-related transactions.

As others mentioned, it's not practical to try and enforce this on people who want to circumvent it, but there is certainly value in improving convenience of accounting for those who want it.

The Intuit-for-Bitcoin market is still practically non-existent, so expect to see more such announcements as the promise of Bitcoin's legitimacy continues favourably.
