I’m not sure the 65k you quoted is accurate. A few years ago, it was half that, but I agree, 65k baht is fairly steep for sure. And yes, I believe most use agents for one of two things. 1- convenience and no annual hassles at banks and immigration 2- keeping the 800k at making 5%+++ which would earn more than the cost of annual renewals.
I wonder if the new DTV will draw some attention from retirees who suddenly become digital nomads or cooking students?
