I can’t speak for Ryan or the team, but speaking from the perspective of someone that has attended classes at Mirai for the past couple of years, I want to say that the majority of the material in the garden is similar to what you see on the sale. Granted it’s not all potted up or all in refinement, but a lot of it consists of big trees. Also, it’s already several people’s full time job + students to maintain what’s already there. Not sure how they’d find the time to dedicate to adding more 
. And really, would a whip with 20 mins of styling REALLY be a Mirai tree?
If you’re looking for raw material with good bones why not give Telperion a call?
I also want to comment on the ‘elitist’ thing. Not everyone that attends in person classes is super-wealthy. There are a very diverse group of students that attend in person. I personally had to plan ahead and make sacrifices in other areas to commit. I knew that I wanted to take my education to that level. I take everything too far 
.
