They didn't say how big in square feet the modular units are, but 13 acres is a lot for 200 units; each unit can have more than 2800 sq. ft. of land area; more than some zero lot homes I've seen on West Oahu. Any fees charged for water, sewer and electricity or is everything absolutely free? And how long will people be allowed to live in them? Is it permanent? Once you move in, no need to move out?  Lots of unanswered Q's. 

I like the general idea but at the same time, it can easily be abused or it can create non-motivation to work and be productive (i.e., "If no need pay rent and utilities , no need work" kind of attitude). That's the only thing that concerns me, kind of like the effect of "having too much welfare" can be a disincentive to go out and get a job to support your family.
