It is clear that to comply with the legislators' guidelines, as licensed exchanges, they had to comply with legal requirements or guidelines from legislators in the countries where they are registered and operate, in this case, Korea and Japan. It's hard to believe that this happened in Japan and Korea because I thought these countries were very cryptocurrencies friendly, especially Japan.
This is good that has only impacted XMR on a relatively small "regional" scale and still, interested traders from affected countries can buy Monero on other more decentralized and P2P exchanges

You made a point that cryptocurrencies will survive and develop further over time. Of course, privacy coins like Monero will act in the same direction but there are different levels of developments and acceptance from authorities and locals. Basically, authorities always want to control as many things as possible so it is very normal and understandable to see them trying to control privacy coins.
Fortunately, I have a belief that people always want to be private as long as they don't have to self-set-up so many technical steps just to get privacy. That is not what they have to do with Monero. For things related to authority regulations, locally and globally, who knows but like I say I believe Monero is strong enough to survive over any type and level of regulations.
