Automated bans can be an issue, but that's an edge case. Google already had the functionality to 'revoke' an app if ordered to do so by a legal authority.
It is much more important to make a real world attack - something that is draining wallets of ordinary people across Thailand/Brazil/SEA in general - harder to achieve. One thing is a political goal of some people in the west, the other is an ordinary person not having the money to feed themselves because a scammer stole it all.
Google doesn't have the ability to change the way banking apps work with regards to transferring money from one account to another in Malaysia/Brazil/Thailand. That would be a matter for the national Governments. This is the best approach available.
