IMO, a big issue is that in many capitalist countries, fixing homelessness by simply providing homes for those without, even very modest, small homes, isn't going to solve the problems that made those people homeless to begin with.

To my best understanding of all available data, nobody chooses to be homeless. It's not like they go out one day, buy a tent, pick a spot on the sidewalk and say "I'm going to live here now". It's usually a combination of bad choices, and circumstances that caused them to become homeless to begin with and a mix of abandonment, lack of caring, drug addiction, and mental issues, that keeps them there.

Bringing homes to the homeless in capitalist countries just converts the homeless into people who live in subsidised slums, with all the issues that come with that.

The homeless also need a variety of other civil services, like drug rehab/addition counselling, mental health services, psychiatric help, medical services, and social supports, like social groups, to help build community among the people who are struggling.

All while the homeless are incapable of paying the bill. Given the conservative mindset, they're "at the bottom" for a reason. They didn't try hard enough, or work enough, or whatever, which landed them squarely at the absolute bottom of the capitalist ladder. To help them up, is asking everyone above them to stop, or lean down or go down to pick them up, sacrificing their hard earned "position" on that ladder so that people they don't know can have a chance.

In the same way, it increases the competition for where you are and want to go on the capitalist ladder, making it more difficult for them to climb up to "where they belong".

I don't subscribe to that thought process, but understanding it is important to know what we're up against if we want to impose changes that make a real difference to those that are homeless and struggling. I'm certainly in favor of it.
