This sounds like a great model to try out in newly-built, 'experimental' communities. Retrofitting existing ones would require more cooperation among residents than you could achieve, I think, except in unusual situations.

I am sure there are large numbers of lower income people who would be willing to try something other than a crappy apartment in a bad neighborhood if the per-month costs were similar. You'd need to deal with transportation issues (i.e. better buses, shared small electric vehicles or bikes, etcetera) and some other things, but it could be a promising method to explore.

Some people might even be willing to try things like a https://en.wikipedia.org/wiki/Urine-diverting_dry_toilet (incinerating toilets may be needed instead depending on the area) or agree to lower electricity usage for a reduction in monthly fees, among other things. I've been thinking about this idea for a number of years, and am somewhat surprised we haven't seen efforts toward it yet. Maybe I should do something.

Yeah probably tough and expensive to transition existing neighbourhoods to this model... but is abandoning the current infrastructure and starting fresh more expensive than maintaining the already expensive existing infrastructure? Don't know.

I do know London, England is build on top of many many layers of obsolete sewer systems from a millenium of city living. Sometimes its best to abandon and rebuild.
