Attorney General Leslie Caldwell "Commerzbank committed these crimes even though managers inside the bank raised red-flags about its sanction-violating practices.."
Forget about their previous infractions, they're going back years are don't involve cryptos. No one suggested they were bitcoid related, so you're arguing a point that was never made. They, or at least some of their staff clearly chose to ignore their obligations in identifying the source of funds. That's a different matter. Their current attempts to clear up their reputation mean they are now perhaps going beyond the minimum required to comply.
As far as your other examples above, it appears a mixed bag. Australian government appears to have given green light for trading but banks are somewhat hostile.
Such is the nature of choosing a few examples there are others. I don't see evidence of hostility from the banks though, I think it would be fairer to say they are nervous and unsure how to proceed.
The question is important as, as citizens in purportedly free and democratic societies, we should have the right to buy and sell what items, products and services we see fit, subject to their legality.
That is absolutely correct, and I don't think anyone is suggesting it should be otherwise, the challenge that needs to be addressed here is how financial institutions can meet their AML and other obligations with cryptos, where these institutions are unable to trace the source of the money. As mentioned multiple times, this really should only be an issue for large transactions, but for some reason some banks are choosing to be more conservative and refuse crypto based transactions. That issue needs to be addressed.
Any notions of banning bitcoin, or crypto, are way off the charts and in total contradiction to the concept of free societies. If we ban bitcoin, then what else?
I haven't seen anyone suggest that.
