Why do people want banks to adopt it?
So that you can pay in a currency that is widely adopted like Euros.
If it is worthy in its own right then people will always want to trade for it, and the ability will arise without permission, starting off with such begging seems like shooting oneself in the foot.
I think we have enough evidence from 15 years of failed crypto-currency adoption for actual payments to conclude that the approach of Taler is more likely to succeed.
But success isnt just being popular when it comes to politics, it has always been known that one can make compromises to become more popular, but the compromise then makes the success unworthy.
