As an aside, look at the way the Germans managed to build airplanes at
the end of the war-or the way huge mine trucks are built today. Most
are built in buildings that the assembled truck could barely fit in and
certainly never be driven out of without dismantling the building. I'd
say you could build a light aircraft designed for manufacturability in
a building roughly the size of a McDonald's and truck them to the
airport with a bread van.

Any mass produced successful sport aircraft today ought to have
folding wings, whether it's trailered or if it goes in a community
hanger. There is a folding wing mod for the venerable Ercoupe (it's
STC'd or their equivalent in Canada, I'm not sure here) and five or six
of them will fit in the hangar footprint of a Skylane.

In fact, there's a hell of a case for combining such an operation with
either an A&P school or a sheltered workshop-don't laugh, Rosie the
Riveter was only one of the famous nontraditional aircraft workers in
The Big One. Doug the Dwarf, Roger the Retard, Crazy Chuck, and Ollie
the Old F*** were there too!
