Re: It's all a bit farcical, isn't it?
That would probably work well for home users, with limited devices on their LAN and the privileges to set networking on the machine.
In business environments, there are a lot of devices requiring IP addresses, which DHCP makes manageable without much human intervention. Very often, usually and ideally almost always, end users in business don't have the privileges in Windows to manually set a static IP, so it comes down to IT support to go do it for them. It's a lot of grunt work for small teams and because of the nature of it, being networking, can't be done remotely.
