Removing it or disabling would probably leaving you wondering why you can't delete that question when you could others, and then you'd have to ask or search on meta why. It's better to let you try and then tell you.
From Don't hide or disable menu items
A long time ago, it became fashionable, even recommended, to disable
menu items when they could not be used.
Don't do this. Users see the disabled menu item that they want to
click on, and are left entirely without a clue of what they are
supposed to do to get the menu item to work.
Instead, leave the menu item enabled. If there's some reason you can't
complete the action, the menu item can display a message telling the
user why.
