there is a lack of context

[lkjhg811]

While Wilde claims there is a lack of context in the video, the amount of times the story has appeared to change is enough to raise some eyebrows.

It seems to me that, in this case, "there is" is not used to say that a lack of context exists or happens.
What's the exact meaning of "there is"?

 

[sound shift]

You're right that a lack of context cannot "happen".

The meaning is simply: "While Wilde claims that the video lacks [verb] context ..."

 

[lkjhg811]

Is "there is" meaningless? What is "there is" used to indicate?

 

[sound shift]

It's not meaningless. It's there to indicate that a lack of context is observable in the video, according to Wilde.

It seems to me that "there is " is not used to say that a lack of context exists.
I would like to hear other people's opinions and views.

Flip the words.

- While Wilde claims that in the video there is a lack of context...

=

- While Wilde claims that in the video context is missing...

"there is " is not used to say that a lack of context exists.

It is.
There is a lack of context = A lack of context exists.
You won't hear the latter very often, but they both mean exactly the same thing.

It's like saying "There is a hole in the paper" cannot mean anything because a hole is the absence (or lack) of paper. We can say "There is a lack of X" - meaning X does not exist but the lack exists.
