You are missing the point.
Pre covid oil gas workers were receiving warnings of "do not use visa exempt entries"
Many of those guys were married to Thai.
Or in case of OP over 50.
They had options.
In my personal experience I first came to Thailand already 50+.
I was travelling to Saigon every month for years.
In those days that Thai consulate provided triple entry visa to Thailand.
I was living in Thailand.
At some point the helpful io lady at Saigon consulate said....
"You are over 50. Next time get a non O retirement, you live in Thailand "
