let me explain to you how it is working in a regulated world:
1. You need tax residency to get bank account
2. You get tax residency by having appropriate VISA
Your VISA is declared tourist type of visa, you cannot get tax residency with DTV because you need to leave and reenter before tax residency would apply. IT was made to live and spend money in Thailand, but not to bring your money into Thailand, because this would be a taxable event.
Now, DTV is intented for people to have tax residency outside Thailand incl. their primary bank account. IF you cannot get a bank account because of your country / citizenship situation in your home country, thats what those sanctions are made for. Of course you might not be the root cause of the situation, but sanctions should hit anyone in that country because of a reason.
You can start a company in Dubai, Hong Kong or else to get your paperwork aligned. You are visitor in Thailand for 5 years, you need to adhere to the rules and regulations of Thailand, no matter now many times they change and calling a govt. fraudulent because they don't want unsupervised bank accounts for tourist people which may or may not be in the country right now, is pretty short sided.
