Haha I thought it would be funnier to say that and not elaborate further. But yeah, even though I use it, essentially it’s a western thing - a large portion of the population use bidets or “bum-guns” that are installed into toilets. It’s actually a lot cleaner, environmentally friendlier, cheaper, but arguably at first hard to get used to from a western perspective. But yeah toilet paper has huge industry and money behind it so capitalism perpetuates it.
Bidets are amazing. I had one for years until I moved (current toilet would be rather difficult to install an attachment to) and holy crap do I ever miss it.
I went to Thailand for a holiday, came back a bum-gun convert. For ~$50, we installed one onto our toilet and haven't looked back - there's no need when everything's spotless.
