With this being Thailand, of course there's going to be some wriggle room and variation depending on who you get, but it's a pretty high risk roll of the dice.
Also I guess it makes it easy to do selective enforcement against troublesome people.
If you detach your job from your (real) environment, this introduces all kinds of issues. You don't pay the share to one of the societies you're embedded into, like taxes. You'd have to be registered as workforce - which you're not, if you're a tourist.
(I do side-eye people who refer to westerners working illegally in the non-west as "digital nomads" while referring to non-westerners doing the same in the west as "illegals")
Do digital nomads have employers?
I believe the smoke test for tourist status, as applied to digital nomads, is whether one’s customers/employer are companies with official representation in chosen country of residence. If not, they are (1) not stealing jobs from locals, and (2) actually boosting local economy, infusing it with cash earned overseas.
Possibly hinting at this are also recent programs in some countries[1] that in a way encourage “digital nomadism”, offering terms that are actually more beneficial compared to tourist status (e.g., longer stay times).
[0] Of course, this argument most likely won’t fly if the immigration officer is out to get you. IANAL.
[1] Georgia comes to mind
I tried to fly there on a business visa but I wasn't able to get one because Thailand doesn't recognise a 'self employed' person as a business.
'Inland' renewability is a big deal if you technically have to 14d quarantine whenever entering the country.
