In the15 years I have lived in Thailand I haven’t experienced anyone trying to get rid of me, on the contrary friendly and welcoming as long as you treat people the same.
Never had problems with the Immigration at the airport always found them helpful, particularly as I have a minor disability, try visiting some other airports around the world.
As far as 90 day reporting it takes about 15 minutes per year out of my life, I can handle that.
Not sure about the problem with alcohol I don’t feel the need to buy everyday and the existing hours are adequate for the majority.
Finally I cannot think of too many countries around the world where a fifty year old can arrive visa free and as long as you have 800,000 baht in the bank literally stay forever.
