Yeah but that's not quite the same. The Thai government is just trying to offer what protection it can to its citizens. That in itself is commendable even if its not perhaps the best way to go about it.
I think that is the right way forwards yes. They could do things like show proof of funds, say 5000 baht, before being allowed entry or something like that. Dress code also, try and keep it all above board somehow.
But many thais go off to the border and play in them in Poipet, its been that way for decades. Many thais go to work there too because of it. They might as well give into demand and profit from it.
I don't think so, I have to coordinate with others and children want to play. So unless they have content on youtube and a website I don't see why I should.
They aren't usually bothered these days. I think once I was asked to show proof of onwards travel and I said I was going to Singapore by train but you had to buy the tickets at the station, and they just waived me through.
