Most people will need internet connection to Google specific commands to run or install the most trivial things, and it won’t always work depending on what distro you’re using. Oh you’re using MX Linux? Goodluck downloading a Plex client installer and just clicking it to install. Maybe use Snap but then good luck creating a shortcut with just a right click.

Limux won’t replace Windows anytime soon, not if even enthusiasts need to Google almost everything.
