Two issues. First, homeless people tend to be much less likely to have the wherewithal to prove residency, either due to substance problems, difficulty navigating bureaucracy, or just not having the money to chase down paperwork or a safe place to store it. So hurdles like "being local", essentially whatever it means, could prove to be a huge barrier to uptake of your programs. Second, "solving homelessness" for just one subset of homeless people may not actually provide the benefit you hope for. You might still have tent cities, RV encampments, people using drugs outdoors, etc. Now the people doing that are from just past city limits and entitled to no support.
