I left 15 years ago and have lived tax free ever since, I was 19 at that time. So i prove you wrong I guess. Been all this time in SE asia countries, never worked more than parttime too (just not needed as lower cost of living / virtually zero tax). It's basically like being retired.
I only deal with governments when having no choice: renew passport, my visa + being stopped on the road.
Anyway, to also answer the actual question of this topic: I do feel less and less free in Thailand, as well that anyone at any moment can start some drama or sht against you, even in years from now, always makes it feels it is not permanent. I never feel like this when in Laos, Cambodia or Vietnam or Malaysia, Singapore, Hong Kong.
I guess this all kind of started around 2015 when they started to flip flop rules all the time with visa's too. I recently was so happy they finally made wise decision to change it to 60 days to then now have that changed back to 30 again too.
Then even I would not mind the 30 ones, then the question is did they get instructions to be like nazi's again or they just still behave relatively nicely like in recent times with just less days only. Even I can get yearly visa's too or there is always a way, it somehow just still never feels good.
I guess I can only achieve that next level of freedom by living on a sailboat.
