> There is definitely a lot of van life/stealth campers going on here in Seattle, it isn’t hard to notice. But judging by their social media videos, is it fair to call them homeless? It seems like they chose that lifestyle rather than having it forced on them (or maybe it’s a mixture of both?).

This isn't referring to the ones who make social media videos about their lifestyle choices. This is people living in a van because while they've lost housing, they still have a vehicle. The people sleeping in a car at the back of a Walmart parking lot, with a laundry basket beside them on the passenger seat.
