Is there a reason why \"null\" has even been included in the l

Answer 1

After all, if there were no "null", I would have no bug, right?

The answer is NO. The problem is not that C# allows null, the problem is that you have bugs which happen to manifest themselves with the NullReferenceException. As has been stated already, nulls have a purpose in the language to indicate either an "empty" reference type, or a non-value (empty/nothing/unknown).
