Well, right off the start I have to comment on where tourists go. From my experience, you want to be around Westerners, go to the bars and party roads. You want to be around non Westerners, go to wats and cultural venues. Even at high tourist times, when my wife and I go to a wat, oft times I am the only Westerner there, even at some of the most famous ways.
That said, I am in 100% agreement with maintaining at a minimum the present rules governing the sale of alcohol. They are already more lenient than in my home country, so why should Thailand want tourists to act differently here than they would at home? I find the concept that Thailand must sell its soul for the pleasure of tourist dollars (which really do not affect the majority) to be deeply disturbing. And so do Thais.
Over the past few years, due to COVID, my friends and family have been enjoying the beaches and recreational attractions around Thailand. For almost all of them, it is a first. This surprised me, but then they tell me that before there were too many tourists and they did not feel comfortable going with all the "farangs" there. I know many really dislike places like Pataya and Phuket where it seems being Thai is being second class.
