I think part of the whole point is that you are *not* forced to do more than meeting the basic needs of you and your family.  Were you thinking of anything in particular?

Healthcare - Most people don't require significant healthcare cost for the useful portion of their lives.  Broken bones, infections, and bugs are easily enough treated without massive expense - basic medical knowledge, antibiotics, sanitation, and good healthy food solves the survivability health care problem.  As for expensive things like treating-for-cancer (which you probably got because of stressful food/environment), expensive operations/transplants (mostly because you aren't eating and exercising healthy), and congenital defects (perhaps the removal of these from the gene pool isn't a bad thing) - I consider spending money on those things entirely optional.  As such, it is not a responsibility that you need to go work for the man in order to enable.  (And even if you DID decide you NEEDED high quality health insurance, you don't have work a particularly high paying job to afford it, if you don't have the OTHER expenses of a typical person)

Clothing - this doesn't require notable money, just information.  You can either recycle other people's castoffs, or you can use information to create your own fabric and sew it together.

Social needs - This is what the community is for, and why *I* personally, at least, advocate that living in communities is the way we should live.  We NEED social interaction, we need a place to be part of to be respected in, in order to fulfill our natural social order.  The guy in the wiki DOES mention friends and family a number of times, so obviously he has some.  Responsiblity for friends and family?  The ability of hands and the generosity of advice is available from everybody, if they choose to give it.  This is no responsibility that is a burden due to lack of dollars.
