If I'm not mistaken the next South Korean president is a liberal so obviously he could be a pro-Bitcoiner after all. Against the left wing party he had to against in the election, it was very close and we don't know if he didn't win. I'm not really sure what he means by deregulate, the law has already presented itself as vey effect in South Korean already, so there's nothing wrong with the regulation of the government as far as crypto goes.
Even I do not understand why the op is saying deregulate. The new president, Yoon Suk-Yoel in his statement said that he hopes to attract more crypto unicorns into South Korea and many bills are under consideration regarding the regulating cryptocurrency.
