I'm sure you mean well by posting this comment, especially given the "very tiny" qualification. However, this is a quite common straw man argument that homeless people are choosing to be so, rather than finding it the least bad of their terrible options.

The problem of involuntary homelessness and lack of access to adequate facilities, health care, mental care, transitional assistance, etc. is so large that to get hung up on some mythical dystopia where people are forced into homes is worse than a distraction; it actively aids those who for whatever reason do believe that for currently homeless people it's a choice or the result of their own bad decisions or whatever.

I seriously doubt the metrics used by the Finnish government would encompass such "wanderers by choice" that you're imagining. They are instead talking about people coming into shelters for assistance and helping them find stable housing that they can rely on.
