> Smell problems aside, how do you transport the compost away from the toilet?
The Night Soilman (https://en.wikipedia.org/wiki/Night_soil) or dunny man in Australia would come and collect it once a week. It really wasn't that long ago in some parts, Brisbane Australia had them until the 70's and it's still within living memory of much of the developed world. In many older cities you'll still see little lane ways between rows of houses that were used to give the carts access to the outhouse, most have been converted to footpaths/bikepaths these days.
I wouldn't want to go back because the smell in the summer heat was legendary, but flushing toilets are incredibly recent.
In centuries past, night soil was used as fertilizer and there was a business case for collecting it. Today, human waste is avoided as fertilizer for a number of reasons (hormones and other medication residues, pathogens), and so there is no more business case for collecting it. One would have to advocate solid waste collection as a new public utility, and that might be an uphill battle.
