I think the issue is that in this case the municipality does not have a functioning sanitation system. Requiring that the municipality implement such a system would require a pretty massive outlay of money and would likely be a tough sell: the state would need to require it of the municipality and somehow fund it. That said, you make a good point that landlords (in many cases) extract as much "value" from their tenants as they possibly can. If they knew each tenant was getting a fixed amount of additional income we could expect them to increase rents by approximately that amount and that would be bad. My example was optimistic in that it presumed this would not be the case. I do think my basic idea is sound: if people had a basic income of a certain amount, then we could expect systems supporting those people to improve (to some degree) by a portion of that amount.
