> I never find myself just randomly inserting characters.

Hasn't it ever occured to you trying to insert a space at your mouse but your cursor wasn't there? People sometimes forget to click (or think the cursor is already there), myself included. Characters are easier to spot because they are not invisible and random letters cause compile errors.

If it has never occurred to you, then good for you. However I do not see what the benefit of not using closing brackets would be.
