From the opinions I hear from many Thai people around me, he would do great if he reopens. Especially after all those promises of reopening. Now everything looked as if they will reopen, and then this guy stands in the way.
I remember 15 or 20 years ago when Thailand said exactly the same thing. They wanted to do away with the backpackers and go after high end tourists (and they've been saying it in various degrees since).
Lately, it's been more along the lines of 'get rid of the sexpats and go for the wholesome milk skinned families.'
So be it. Let them try. The market will decide. Backpackers still come here - despite the crackdown on full moon parties and rising prices. Sexpats still have a decent time despite their best efforts to implant a 7 eleven and mini-mart where every bar once was, have early closing times, and restrict liquor.
I've been to a number of high end destinations and Bangkok doesn't really fit in with that group. It's sort of like Manila trying to be Baden-Baden or Monaco.
