I did not presume a conspiracy. As an anon on a forum populated almost entirely by other anons, no one needs to justify why they might want their privacy generally speaking. But you are asking people to trust you and give you money. That changes the equation altogether.
Virtually everyone who teaches anything on any topic throughout the world manages to use their own names without people showing up on their doorstep. Primary teachers, professors, martial arts instructors and even people teaching internal arts.
So I don't buy a random person taking on the enormous expense and hassle of flying to China (or wherever) to bother you at home is a legitimate concern. This is an area of teaching with a great deal of fraud it seems unfair to label sensible caution as a conspiracy.
That said, you avoided being super defensive in your response and that's a mark in your favor. I also appreciate that everyone has had all sorts of weird jobs in the past and it is not fair to judge you on that basis. Last, I'll concede that your TCM training isn't directly relevant to what you teach.
