Sure, I haven't had to live in a tent and poop on the street and I haven't had to live in a warehouse type of scenario where I did not have to poop on the street. If ever given the option (without having ever been in either situation and I was a beggar needing to chose) I would opt for the later. However, if I ended up not preferring that I would have to opt for the tent on the street (since that option would be open to me too) whereas the other might not be because of limitations in size. But I would prefer the security (whereas on the street you are on your own) in fact many homeless do not like homeless shelters because they have experienced theft or harm because there was no security.
Sure, you can only make the best guess you can, and if you guess wrong (opting for the over crowded concrete shelter with meals and bathrooms) you at least could opt for the streets (without meals and bathrooms). Now, I have a bad back and so squatting to go to the bathroom anywhere would not just be difficult but impossible for me and so I know I would not prefer that so my choice (confronted with that) remains the same.
Reacting to a shelter against the elements and some sort of violence against yourself isn't really apples with apples.
People who break the law and are in prison are fans of freedom to go wherever they please and would likely prefer better food, but I think not following the law actually got them into where they are most often than not and sometimes when lawlessness abounds the prisons can also be stretched beyond capacity and that becomes problematic also. But I don't believe illegal immigrants have been kept as prisoners and are free to leave, to even chose to return to their home countries or another's.
They are free to do drugs, the free needles support it. And sure, we can see all that supposed social support all over the streets (how thankful we should be).
There are surely better on line definitions, this one is rather weak but I see what you are trying to do.
