And it’s still not like you’d be quite as clean from dry wiping even if you have perfect poops.

If someone touched a poop and then wiped their hand with a piece of paper, I still wouldn’t shake their hand.

No, there’s always a level of unavoidable fecal matter and this is normal and good in some instances (e.g. oral consumption of probiotics to support a healthy vaginal microbiome) - and conversely some people are blasting their anus with water jets so frequently it causes issues, for example

However, excessive bidet use potentially causes anal pruritus and anal incontinence (AI). Physicians are advised to instruct patients with anal pruritus to avoid excessive cleaning of the anus and those with AI to discontinue bidet use. For the estimation of the inherent severity of AI, physicians should instruct a bidet user with AI to discontinue bidet use and assess the severity of AI later. Additionally, the nozzle surface and splay water of bidet toilets may be contaminated with fecal indicator bacteria, such as Escherichia coli and Pseudomonas aeruginosa, as well as antimicrobial-resistant bacteria, rendering them a potential vehicle for cross-infection.

That said, it’s funny that the fucked western diet also accompanies the worst pooping position (sitting instead of squatting) and worst cleaning mechanism for bad shits (smearing with paper instead of literally anything else)
