> (they need someone who will sell stablecoins in their currency).

It's pretty hard to really lock people out of stable coins really. You really just need someone to sell you some type of cryptocurrency that can be eventually exchanged for stablecoins. You can even do "peer to peer" trades if the government really cracks down on holding crypto.

I agree with the sentiment of this article but atleast some parts of the world with poor currencies like Latam have seen some benefit from stbales.
