Whether it's for economic (less spending money), technological (mp3s are a lot smaller than CDs), or simply cultural reasons, the younger generation seems to have less stuff.

I see an opportunity in 5-10 years...microapartments in former self-storage space?

Some people already run mail-order businesses from self-storage units:

This seems like a more likely outcome than living spaces. If for no other reason than a lack of water/electric outlets for home use. Air-conditioned storage units could make decent (depending on location) store fronts as well, in a sort of industrial mall sort of way.

It's hard enough to get the governmental approval of microapartments in buildings with more normal residential design. (Depending on the location of course.)
