You need to read my comment about VOA costing 2000 baht for 15 days which is correct. You tried to tell me it was free and 60 days. FAIL! You've much to learn about Thai visas
It is possible to be a dual tax resident with another country. If you have closer ties to that country under a DTA, that country's tax laws prevail. Now THAT is what a lot of people are overlooking. However you are trying to spin it, you cannot be double taxed.
There is a lot of bitterness towards this new SuperVisa. Many Digital Nomads believe it's only for them and they're getting stroppy because everyone is applying for one. I know one guy who got a "dental treatment plan" which is essentially four fillings, some x-rays, clean and scale spread over eight months and he's scored a five year visa out of it! Good on him!
