Yeah when testing I have removed myself from the admin list firsts.
I've tested this by trying the command object workbench2 1 - which as expected I get a a "you don't have permission" message in red. Other commands are blocked too as you would expect.
I then go to my workbench (seen in second screen capture) and the workbench2 isn't listed as locked and you can still make/craft it.
I've also tried this for other objects and they too seem to display the same "symptoms" i.e. message on the console and ability to craft the item in game. counter1, counter2, counter3 etc
