Homeless people has been something always considered a problem needing a solution. If you are houseless, you are homeless... or so we were taught.
  I was surprised to learn not all houseless people feel they are homeless. 
  What is a home? That definition varies from person to person and will definitely vary from state to state with laws and regulations.
I see a home as a place to be at the end of a day, a place you can relax and feel comfy.... not the same for each of us. A car, a van, a camper, a bus, etc... so many different ideas of what can be a home. 
  How much time does the average person really get to spend in a home? For me, not too much since I am working full time all week long and others work more hours than that.
  How much work does a home take to maintain and keep it nice? Is that too more than it's sometimes worth when you still aren't just at home, enjoying it? 
  The cost of a home...house. Taxes, mortgages, rent, utilities... enough people are now seeing a lot of their paychecks go to just having a place to live. 
  I'd love a camper home... maybe travel around a bit but keep my job. Maybe pay to be at camping parks in the area. I don't know. It's something to think about when you actually THINK about it. 

I will not agree that people living in tents on streets or public places are just houseless... I see them as homeless and many have nowhere to keep their belongings..not even a vehicle. Many most likely don't even have a job. 

Some vehicles that people live in are stunning homes.
And with the cost of living crisis and everything, I can understand people going down that route, and yes, I also get the freedom bit. You can spend the night where you want and travel around and yet are "home" every night.
The cost of running a bricks and mortar home is astronomical now and probably only going to get worse.

Tents are not secure or safe for living in full time.

To be honest, I am not sure how people here access a lot of government stuff without having a fixed address. Driving licences etc are supposed to show your photo name and address. Same with vehicle registration documents.
There must be a way around that but I have never thought about it before.

@KieranT It's an interesting thought about a fixed address. I hadn't given that much thought. 
I have my thoughts and theories on all of that!
