Tours are nice for people who are close, but even a group of people is not as efficient as pictures and videos that 100s of people can watch/look at for one piece of work. I do not know all of your reasons for wishing privacy, but I can think of enough for wanting my privacy to suffice

Should I ever be in the area (travel would take away from resources I would rather put towards my own project) and know that I had something to offer in the way of work.... and it worked in with whatever you were doing I wouldn't mind paying for my stay. But I expect I would get more out of lots of videos... probably even more out of a few pictures and lots of words. Podcasts don't work for me, I can read faster and hit less rabbit trails

(perhaps that is also why videos don't grab as much). Work shops are great, I learn by doing as well as the next person.
I think that people who want tours are trying to get the benefit of a workshop (or a group of them) for nothing, (both in terms of money and time) and are probably ripping both you and themselves off.
Just my opinion.
