Rather than guess as to what his business model may or may not be, call him. He builds to order for the most part.
I may. I am not shy about sending an email. This is a post trying to understand his business model, in part. That’s allowed, I assume, on the forum. (Not every post is an end user seeking personal advice in the form of a general comment, but thanks for what you’re probably thinking is the nudge you think I need.) Sometimes a forum post is a general comment.
My general conclusion, then, is that it’s odd to have a website where everything is sold out, most of the time; where everyone who wants a speaker is best off ignoring the website. Maybe it leaves people wanting more if they think he has no inventory.
