Ian,
Back to your original point, it's clear that the person who reached out to you was just looking to belt notch some list of courses. It's pretty clear he wasn't interested in spending time with you, but wanted you to sacrifice your time and efforts to help them achieve this goal of theirs.
I think most, if not all, posters on here are happy to share their home courses to those interested. It's fun to share in an experience, especially with fellow golf nerds. It has less to do with where you're playing but with whom, although given this crowd the conversation is fueled by architectural interest. I'd go play with JK at his Florida club, wherever it is, as I'm sure it would be entertaining.
It was a lot of work to set up, but perhaps one of the most rewarding experiences for me was when Jeff Sherman and I hosted a crew of 20 out of towners at WBYC before the 2018 Mashie. Again, it's fun to share the course, but it's also fun to share in the grand experience that is a Super Soup dinner in the golf house.
Essentially, I think it comes down to authentic experiences and requests, and nothing about the original request was authentic.
