Sure these solutions would work. Institute free universal healthcare paid for through the tax system, spend money on empowering women and helping families with children (including family planning), and make education free up to and including college.
To finance it, tax the rich, dismantle 4/5ths of the US military and stop fueling wars overseas.
But that's called socialism and is (unlike actual treason) treated like it would be high treason by the US political parties; mostly because they are all in the pockets of wealthy donors who would not like this new regime.
You can’t force people to accept treatment in US. While these might slow growth of the homeless population in dire need of medical help, it won’t prevent it.
To have no homeless, you have to have both resourcing for housing/medical, but also be willing to use force to compel those unwilling to get treatment/be housed where they have little choice. That’s a very tough leap to make.
The choice part never made sense to me - why would anyone want to live like that? But, as a society we value free will and therefore must respect the choices we do not agree with.
You don't generally have to force folks to get help. We (the US) do it in a small portion of the population: Severe mental illness, dementia, and substance abuse. They aren't talking about forcing folks to do things. You can encourage folks to do such things, though.
Most folks don't actually want to live like that, but some really do want to shun society. You can offer folks things like primitive cabins to help them shun society. Substance abuse, mental illness, and job loss are real problema with real solutions. Heck, if you can't solve someone's substance abuse or alcoholism, you can at least make sure they have shelter and food available to keep them safe even if they won't pay for such things. For a single person, it doesn't have to be luxurious: A dorm setup with private bathrooms and shared kitchen can work out.
