As long as you wipe well, there's really very little bad that can happen before your next daily shower.
Note that I have nothing against bidets, but this argument is not a very strong one.
Over years, how much of it is accruing on your office chair? The fabric of your sofa?
> As long as you wipe well
If you leave that amount of fecal matter on your arse, then obviously it will smell bad and be unhygienic. My pants usually don't smell at all at the end of the day when I go shower.

Probably nothing or very close to it. There's usually 2 layers of fabric between the tiny amount left and the chair or sofa.
TMy office chair of 10 years that I recently replaced because it broke had a discolouration on the headrest from smearing my head on it. The seat was pretty much pristine. My sofa doesn't smell at all after many years of use and has no weird colours.
Also, the argument isn't necessarily about preventing something bad from happening, it's also about just feeling clean. People who have not tried a bidet cannot really say whether they would feel better/cleaner with TP or a bidet. It's like if you tried to explain to someone who has only ever used wet wipes to bathe that a shower makes you feel better. Sure, wet wipes may objectively clean you but those who have used a shower can speak to the subjective benefits of feeling nicer.
The counterargument that "TP works well enough" is not a very strong one to my mind, if there's something that works better with no real downside.
Your poop smells. You aren't getting it perfectly clean. Some people believe they don't have to clean the lower half of their body, which is equally crazy.
