What I understand is that the government determined that the minimum threshold is proportionally the same. If they matched the thresholds, then they wouldn't get anything from crypto traders. If they made the crypto threshold 16k, then the stocks threshold would have to be around $128k. Bear in mind the gov have raided exchanges in korea so many times I'm sure they scooped up second and third cooked books to determine real transaction values.

It's been a long time coming but it looks like they're finally here. Crypto taxes in South Korea.
Took them long enough. Honestly they don't look that bad. it's better than the capital gains threat that was being thrown around for a while.

Yeah I feel you on being uneasy about tracking and flagging wallets. Seems like something a centralized system would have levied on it. That said, countries have their best interests in mind. The crimes being committed with cryptos in SK seem pretty bad so they probably want to mitigate that any way they can.

This company in South Korea is figuring out that once a cyber criminal, always a cyber criminal. They found that two separate big crypto crimes shared the same exchange account for onramping or offramping. Of course most of it was done with Bitcoin. Don't know how it will get better before getting worse.
