Regular toilet paper seems absolutely barbaric after one has become accustomed to wet wipes. Try them and you will understand.
Wet wipes do not biodegrade, no matter what the package says.
When you have to go, you sit down at a waste collection station, and a computer guided arm would connect a hose to your valve and open it. This can be designed so that at no time in this process is anything on the outside of the valve, the hose, or your body exposed to feces. All the feces goes into the hose. When you have been emptied, the valve is closed, the hose retracts, and its interior is cleaned.
That is how civilized people would take a crap (until we reach Star Trek levels of technology...then we'd just beam our feces out).
