Liking something, vs being used to it and understanding how to navigate all of the complications, are 2 different things.  Some of those people saying they do not want the shelters or housing are also the same people that are honest enough to know that they have no real job skills to earn enough money to actually afford a place to stay.  Why bother trying to get a place to stay (starting with the shelters)  when you know there is no end game for you to actually stay inside ?   Some of these guys are just being brutally honest and have become more survival experts than anything.  They don't necessarily like it.
