Much of homelessness is similar to the tragedy of orphans. They need not only a building to live in, they need people to live with and care about them. Things that most people have naturally but some do not. You cannot purchase a supportive family for someone. It is a Catch 22 to try to buy compassion, as if it is incentivized purely by money, it isn't compassion.
That's nice, but you're describing several different problems as if they are just one problem and then saying the one problem can't be solved because it doesn't solve some other problems. While it is possible that homelessness is a result of various conditions which include for example lack of a supportive family, the lack of a supportive family is not a singular cause of being without a house; it's not the kind of thing that can be a singular cause of that. It would be the lack of a supportive family
AND the surrounding social context, specifically the part of that social context that requires people to have bought or to rent part or all of some real estate in order to have their own place to sleep.
You cannot buy compassion directly, but you can facilitate the connection of people such that they may be able better to find it. With money. Also without money, but certainly with it too.
We've already hit this point, where you acknowledged that some things are priceless, and then you immediately retreated to "commodities". How do you intend to explain why I'm wrong this time?
Addressing homelessness-- the condition of being without a house-- only requires replicating the straightforward market interactions that allow others to be housed. It requires nothing that needs any sort of detailed explanation, nothing that should be at all controversial. Nothing priceless need be involved in the construction of a house.
I did not concede that problems that require the acquisition of something priceless cannot be addressed with funding, only asserted that housing people does not require any of those things-- you brought up something irrelevant. But as you insist...
Since you cannot simply buy something priceless, money must be employed in a different manner in order to gain it. For example, by hiring someone (or several someones) to steal that which is not for sale. There are countless examples of that in Canada and the United States with respect to the lands of indigenous people. Indeed, it is unlikely that much of that could have been done-- or indeed could continue-- without the use of money.
Or for another and rather different example, to connect people together such that they can find love and support and all that jazz; dating apps, adoption programs, etc. The problem of wanting priceless objects and even priceless abstract concepts, can be addressed by the expenditure of money.
You want a population to agree with some set of ideas? Buy a news station. Fund the construction of a university. You'll be pitting your money against that of many others, though, so hopefully you want something similar or just have a lot more.
You want something really ambitious like your dead family member back? To the extent this can be addressed, it can be addressed with money-- if you have it-- though it won't come cheap, and you might not see a result in your lifetime.
You want a law changed? Money. Whether directly to legislators in a manner that is easily recognized as corrupt or via some probably more expensive method of public relations.
There is always:
1)Hire someone(s) to figure it out
2)Hire someone(s) to steal it
and these together account for pretty much everything that isn't "just buy it, it's for sale". Unless I'm forgetting something, but that can be addressed by funding as well.
