My thoughts exactly...doesnt make sense unless you are generating alot of organic waste from humans and farm operations. Also, temperature is an important factor...thats why you see alot of these smaller biogas systems in tropical climates where temperature is warm and consistent year around.
Household wastewater here in the US (unless your Mr Natural) also has other constituents that dont need to go into digesters like cleaners, personal care products, pharmas...And I would think you would still be required by law to dispose of any overflow from the bioreactor to an on-site disposal field.
I still think the easiest onsite wastewater solution here in the US is the septic tank and disposal field or compost bin toilet (and disposal field if you want to be kosher with the gov't). I think more of these systems should incorporate vegetated beds so that nutrients can be extracted from the wastewater before being disposed into the soil.
