I think I read the parent comment differently: when crypto is claimed to be a weapon against the west, it is not because it is in any way an alternative, it is a weapon as a system supporting illicit activities against the west (money laundering, sanction evasion, state sanctioned ransomware). The fact that it slow, unscalable and expensive does not matter for those type of activities. So I thought it does not really matter that our banks are efficient.

> It's to say that "West" has a quite established and efficient transaction platform.

That part of "West" you are referring to also had ultra low or even negative interest rates, thus eroding the buying power of Euros and other peripheral currencies. No wonder European countries also account for some of the highest numbers of bitcoin nodes (per capita).
