You would get a null reference exception if you unrolled that into a loop, too. You should know what your data is going to look like and if any elements could be null or not. Don't blame LINQ for your lack of null checking.
I'm suggesting it's feasible but not necessarily perfect and when it does go boom, which it does when you have 100 million HTTP hits a day, you need to be able to find out precisely where it went wrong. LINQ makes that damn hard:
NullReferenceException
Company.Product.Assembly.Namespace.Type.Method() +14
...
When line 14 has 22 dereferences then you have no idea why it broke.
