You never presented the document that DTV other than eorkcatio is exempted from the law forbidding foreigners to do any work.
Until you present that the only conclusion can be that officially you are not allowed to do any work.
That you can do remote work without much risk, I agree, because it is not actually enforced, but that also applies to visa exempt, and all other visa for which work is not allowed.
But maybe you should ask Google with the question "am i allowed to do remote work in thailand" and you will see the explanation what you need.
DTV workcation is one of the visa nentioned, DTV softpower is not mentioned.
