Indeed. I think these two are past the point, mentally, of having hobbies and friends. Not one friend has been interviewed who has spoken to either of them in the past few years. You don't go for a pint and a curry and then return to your tent where your newborn infant is living without heat or running water. MG is wearing plastic bags on his feet at this point, both likely smell rather potent from wearing the same clothes for weeks on end. I think these people are living completely outside of society.
I also think the access to funds is a moot point, because they aren't using their funds rationally. CM had at some point enough cash to buy and maintain a comfortable home, yet they've been evicted multiple times. They seem to have funds to spend on long, meandering taxi rides. They seem to be past the point of using any funds the way you or I would--to secure shelter and get out of the cold. Note that they had access to funds and bought a tent but apparently no property footwear for MG. I don't think rational thought can be applied to these two's actions at this point.
