Good Point but if they get too strict with their rules all the westerners will leave and travel to near by countries. The Thai Governments havent got a great track record with making rule changes. Look at the situation with weed, previously get caught with weed and you up <deleted>s creek without a paddle. Then they changed the rules, there is more weed shops now than convenience stores and then they decide maybe its wasnt such a good idea and they are going to possible change the rules again. I think if they get too strict with residency/tax rule changes they will make further adjustments down the road when they realize they have messed up.
