Yes, you've made the same argument as the article, estimating the impact of producing the toilet paper but not that of producing the bidet. What is the impact of acquiring (mining?) the ceramic and metal parts, and then manufacturing these into a bidet and fixings? I think it's likely that the impact of the bidet is lower by the end of its lifetime, but an argument which says, 'manufacturing and installing a bidet has a similar impact to producing x rolls of toilet paper, and so after y years then the bidet can be considered better for the environment' would be much more compelling to me because it doesn't look like it's trying to hide half of the argument
