Even the most friction-free ClickOnce deployment is going to be more of a deployment hassle than "hey, users, you know how you go to https://subdomain.local-intranet/place to add or subtract items from the inventory database? Well, continue doing that".
The webapp doesn't care if someone's machine was down overnight or if the paranoid lady in design managed to install some local "antivirus" which blocked the updated rollout or if the manager of sales has some unique setting on his machine which for some inscrutable reason does silly things to the new version. If their web browser works, the inventory database works for them, and they're on the latest version. If their web browser doesn't work, well, your support teams would have had to eventually take care of that anyway.

The web browser is not some magic tool that is always guaranteed to work. Group policy alone can wreck total havoc on web apps on all the major browsers.
