I do speak as a person from north america and made tried to cover my ass with the beginning statement of this isn't going to apply for everyone figuring europe or other countries will have different challenges in government and feasability. You do raise some good questions. I get the impression you don't really have any use for my answers though. Someone who measures saved money in frappachino lattes and is so cemented in their particular job they are unwilling to commute long distance, switch jobs, or move to a cheaper area, probably isn't willing to sacrifice any amount of convinence for the kind of lifestyle im advocating. Regardless ill answer your questions earnestly and hope it informs.

For food, you cook your own meals obviously. 12v fridge and house batteries or perserved shelf stable foods. Most people who live in cars have propane or disel fuel for cooking and heat, or enough battery capacity to run a portable induction cooktop and electric water boiler. You can even power appliances needed for your precious frappachinos to make yourself. You spend free time at public parks and nature reserves, go hiking, camping, find things to do besides sitting around in one place. On bad days you still can hang inside the car. In north america theres a lot of free public land for recreational use and free dispersed camping especially out west.

Having a mailing address to put down on govt and banking paperwork is a challenge if your home is your vehicle. There are ways to get a mailing address and there are mail forwarding buisnesses that you can use. I think the endgame scenario is you would eventually get a plot of land and register a mailing address.
