That's not enough, well it might be enough in the US, but here in NL people who are officially Dutch or have been through the process as a refuge to get housing and food etc. Should have at least some kind of shelter.

Then there are still the like 2 (estimation) people in this country who choose to be homeless for whatever reason. I don't try to judge, but there might be some mental issues involved.

And then there are the people who came here from other countries, but haven't gone through the official channels. Some of which came to work, lost their job and cannot find somewhere else to work. Generally this group has housing paid for by their employer, but if you don't have one you don't have a house, at least not here in NL.

There are probably other examples in other countries where basically everybody can have some place to live, but there are still homeless people. I don't believe you just need free housing, you probably need some extra social security and the social opinion on homeless people or people who are at the bottom of society needs to change.
