You have good points here, and this reminds me of MasterCard getting giddy with pornographic transactions, even in areas where it is fully legal. However, I think that cryptocurrency will only solve 3) in your list.

For 1), they often seize everything, to the point that they seize computers and phones. Even if they are smart to have a backup, I'm pretty sure that they will try to hoover up anything and everything, even regular currency.

For 2), I think that this is a societal problem, really. In France (as an example), you are entitled to a bank account regardless of your status, that even means if you have been convicted of money laundering. On the flipside, and I am assuming to use cryptocurrencies like Monero which makes transaction tracking harder, if you are really wanted you could end up in situation that I described on 1).
