I was looking at prices for a small room in Manhattan storage. The price of a room slightly bigger than a double-size mattress is $150/mo, for a pretty central location. YMCA membership for $40/mo for your running water, and bam, an apartment for < $200/mo in Manhattan. Sure, it won't be cozy, but I wonder whether it'd be feasible to have crazy-cheap housing like this.
Quasi-related: There are some people in my neighborhood in San Francisco who have apparently been parking their junky RVs along the curb for years. Occasionally I'll walk past and they'll have a generator out on the sidewalk charging their batteries. Neighbors have complained, but I guess it must be legal, because they're not going anywhere. Though a really ghetto solution, I've often wondered about the feasibility of bootstrapping in an RV :) Or maybe a sailboat.
On a related note, suppose I share my music collection with my friends (a ka the internet). How will I then know which is my music? Has that problem been solved to a satisfying degree yet? Forgive my ignorance, I am still struggling with iTunes (MP3 collection not yet fully tagged), so I am not sure how it works these days.
