Indeed - they are also easier and simpler to replace as needed - and take less looking after. I wonder how long these will last without upkeep? How far can they be pushed, and if left static, where would they be left without risk? From my own observations, I'd say that owning big 'things' like this is just going to cause trouble for the average homeless person. If it is 'good' then they will be at risk of others on the street taking it from them, or passers-by destroying it for fun. Also not sure I'd want to be inside something like that with the kind of people you get in city centres at night, walking by - people have been known to set fire to sleeping homeless people, or at very least urinate on them. So this could either be a perceived risk or something that you might not want to use after a short period. Remember - people sleeping rough aren't /just/ looking for somewhere to sleep. If they were then they'd be camping out in the woods etc (I know some do), but often they have other issues (drink, drugs or mental health problems) and they base themselves centrally to have access to drink/drugs/money/support. While I applaud the concept, I'd far rather see some more holistic support for the 'homeless'. And while I'm left leaning, even capitalists should see that costs of not supporting those with issues, can be far higher than the cost of supporting them (I read before that the average homeless person 'costs' Camden council (who look after Soho in London) about £16k - while those they can get into a hostel and provide support to 'only' cost about £6k.
