Do you consider someone homeless if they CHOOSE to live in a tent or van but don't need to?

I watch an awesome guy (imo) on youtube who lives in a hammock pernamently in the UK. He has the money not to, but he just likes living in nature and being a hippy.

If my husband wasn't so big on keeping our house, I'd be living in a converted micro van by the end of the year.

My husband doesn't consider the micro van homeless since it is converted but he very much considers people choosing to live in tents as homeless because it's a temporary shelter. He says chucking temporary stuff in a car like a matress and your cooling stuff and whatnot is also homelessness, even if you enjoy living that way petnamently.

I disagree because neither are in a home so to be me either you consider anything outside a stationary structure as homeless or homelessness is just to do with whether the home you choose is by choice or not. The latter is how I define it personally.

Doesn't really matter. If the tent guy is happy and you call it homeless, doesn't change its still clearly great for the tent guy. Homeless just generally makes people think of people desperately in need of a home, hence I don't like defining it as that.

Thoughts?
