Yea, I mean you're not particularly free if you can't sleep anywhere without either drunk people assaulting you or a land owner kicking you out, or if you need to constantly worry about finding electrical outlets just to keep your phone charged or worry about finding a tap or water fountain to get water. And you're never able to eat actually pleasant food because you can't even access a cooker or even a microwave/toaster and you almost certainly can't afford food that is prepared for you.

I can only imagine their image of being homeless is having one of those vans that cost like $40k USD to kit out with pretty much everything you would have in a house... in which case yea I guess that would be pretty liberating but you should probably specify that if it's what you mean.
