"Waking up in my cardboard box under a bridge, listening to the ducks quacking happily, the lovely fresh air. By jove missus am I happy. :-)"

Well of course there's quite a lot to say in favour of a more minimal lifestyle in which people are 'closer to nature'. I know a number of people who do it in their own way - on boats, in vans or in Tipis and so-on. The major obstacles they face in being happy with their minimal non-consumerist lifestyles are the police who move them on, councils who tell them they can't live in that caravan or tent. No, not there. You're breaking the law. Cardboard box under a bridge? Move along, move along.
