Putting a burden on people who aren't able bodied is harmful to them, because it means you accept some threshold of fasle negatives -- people who aren't able bodied but who will not qualify for the support. What will they do? They can't work because they aren't able bodied, but they can't qualify for assistance because the government doesn't think they're broken enough. That person will become homeless, and then their existence is essentially criminalized in many places.
