"LET ME ASK you: why would you be so stupid and book a soft power course, if you already fulfill the requirement to apply for a DTV based on being a digital nomad?"
Because it's very possible to work remotely and still not satisfy the application requirements for workcation. You need to have been doing it for a signicant length of time, for example. If you've only been doing it a few months then your documents won't be sufficient.
