> Unlike BitCoin or cash payments, Taler ensures that governments can easily track their citizen's income and thus collect sales, value-added or income taxes. Taler is thus a currency for the mainstream economy, and not the black market.

This simultaneously implies that both Bitcoin and cash are not suitable for the mainstream economy. I think the opinion that cash should be given up would be fairly controversial, even today. Furthermore, a law abiding citizen will still pay taxes on their Bitcoin income - the same way they would for cash. Just because Bitcoin makes it harder to prove tax evasion doesn't mean we should eschew Bitcoin and cash. The technology exists regardless, governments will have to adapt.

> When you pay with Taler, your identity does not have to be revealed to the merchant. The bank, government and mint will also never learn how you spent your electronic money. However, you can prove that you paid in court if necessary.

This feature is offering nothing not already available, although it seems to imply that one could not prove payment with Bitcoin, which is false, as it is trivial.
