I understand what you mean. I can give you an example from Italy, there is a register of italians resident abroad, if you register yourself here and you can don't stay in Italy more than 181 days, you will not have any problem.
But for DTV and other tourists visa it can still be a problem because Thailand don't give you a "real" residency, so you may have problems still because you can't even really "prove" to your country that you are a "real" Thai resident...
So yeah, thinking more you are right, this can be a problem in more ways...
but in most of countries you have to stay at least half of the year to be considered a tax resident. So if you stay more than half of year in Thailand and you can prove it, how other countries can claim that you have to pay personal tax to them?
Except maybe US but for Europe this should not be a problem
What is the problem paying tax in Thailand? You have to pay tax somewhere. Income tax in Thailand is not higher than other countries. And you should not double taxes in most of cases
