I understand where you are coming from. The old Owner account used to be like that in XP. Also in the old days Linux installer used to dump you into a console with root privileges on boot-up. Trying to appeal to the non computer professional/super-user they changed to a user account with limited privileges. I'd like the way they did it if it wasn't for the UAC thing. That's too annoying for words.
On Linux you don't have to "activate" root. Just hotkey to a console and log in as root or use the
su command in a console window to get all powers. At least that's how it was last time I spent any time with it. I'm too much a product of Dos/Windows/OS2 to be comfortable with Linux editors. The word processors that are "Windows like" never feel comfortable to me. Usually it's a matter of trying to get a Windows editor to work under Wine. Too much hassle.
Although if I was running a web server for money I'd probably use Apache.
