I think part of that larger discussion needs to include the array of reasons that people become homeless in the first place, cause it's not just that they lack motivation like your comment suggests. There's mental health reasons, financial reasons, drug addiction, alcoholism, etc. And once you become homeless, it can be difficult to get out of - jobs require that you have reliable transportation, and an address for mailing stuff to you, that you look presentable, and that you don't smell.
A fair amount of homeless people have smartphones nowadays, so I think a system in place where temporary residence can be set up, a bank account set up, access to therapy, and priority access to remote jobs can take place will be a huge step forward in reducing the homeless population. That and also capping interest rates and market values for houses/condos/apartments so that they're actually affordable to the common person.
