> can eating soap give us some of those benefits for viruses that are already in our bodies?

I think the thing people are missing in a lot of these comments is that viruses are typically traveling from the skin to a mucus membrane in your body (which can be in the stomach but also in your lungs and nose), then infecting your cells. Eating soap might impact pathogens in your still in your stomach, but it's not going to dissolve in your blood and circulate through your body at high enough concentrations to impact viruses...

...and if it was high enough concentration: imagine snorting, inhaling or injecting dish soap.
