Maybe you don't get my point or you want to keep seeing things wearing your western glasses.
For instance, over the 15 past years in Thailand I've seen personally many people living from stock, forex and lastly crypto trading (remotely, nothing linked to Thailand). I've never heard nor read︀ in the local news of some foreigner being caught/fined/jailed because he was "working" on his︁ computer while at home. Did/will it happen?... possibly, however it should be a really small︂ number of people certainly involved with other issues (money laundering, drugs, scams, ...).
Nothing's certain︃ in this current world (regardless the country you live in) and when you make a︄ decision you need to assess pros/cons as well as associated risks. From my own experience︅ risks associated to "discreetly trading online while residing in Thailand" are still very small, for︆ now.
If tomorrow things change then, of course, you will have to adapt and move︇ on. But this is valid anywhere in the world including EU or UAE where rules︈ can change in a finger's snap and law enforcement is not as "flexible".
