Well, yes and no. They might have been more willing to accept that 30-40 years ago, but definitely not these days. They've been always known for militant labor unions, religious fanatics, and political extremism -- the last two attributed to the outbreak in South Korea this time around. There are still religious groups defying the gov't's plea not to hold mass services in South Korea today.

South Korea suffered a much smaller coronavirus, MERS, not too long ago and they found out that they were awfully unprepared for a public health crisis of that scale (only 130+ were infected and 30+ death), so they spent the next several years preparing for the "next" crisis. Their gov't removed all potential legal/legislative barriers that had hindered their response last time around and private biotech companies started working on reagents and the medical infrastructure almost as soon as the outbreak in Wuhan became known.
