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.
