Read TFA and the press release linked therein. If you're a "digital asset exchange" operating in Thailand, offering your customers to trade the banned items will lose you your license, and if you continue operating I imagine at some point the police will show up at whatever physical presence you have and arrest people, and your assets (including bank accounts) will be seized. No, that is not 100% effective in stopping people from trading these coins, but it doesn't have to be, and it' not even necessarily the intention - note that it's not even a law but an SEC decision.
