it's fine if the Indonesian government wants to do it, taxes are indeed the biggest income as an asset of the Indonesian state, As far as I know all crypto exchanges, official ones from their government are legally licensed to operate in Indonesia, registered.

Maybe the current government is aware that crypto users are growing very large in Indonesia, you can say billions of transactions per day, here may arise a thought for the government to carry out a 0.1% tax rule through VAT or PPH.
