Depends on the person, lifestyle, and season. Plenty of people need daily showers but you’re sedentary, indoors most of the time, and not very sweaty for example you can strip your skin barrier by showering too much. Multiple showers daily especially can be quite bad for your skin.
Full time desk jobs often cause people to be sedentary. I think you’re also really overestimating the level of sedentary I’m talking about. There’s a lot of perfectly normal people who benefit from showering several times a week instead of daily. Here’s a link to another article from Harvard agreeing with me. https://www.health.harvard.edu/blog/showering-daily-is-it-necessary-2019062617193
