My former business partner needed a place to store his Piper Cherokee airplane. Hanger space at his home airport (Bennington, VT; William H. Morse State Airport, DDH) was either costly or limited availability. Long story short, he got some kind of ground lease from the state for 99 years, then built a 4-place pole-barn hanger. Sold three shares as "condos"; kept the fourth for himself at no cost. A few years later he sold the plane, and separately, his "condo share". If you think classic cars are a rich man's hobby, ask a private pilot...
Here in Michigan some investors got together and created condo-garages for storage and built a track too.

So, the business model is there in several forms...it just takes time, money, perseverance to make it all work.
