What is wrong with this premise?

[Heywood]

I found this interesting video on the subject that explains this better than I can:

Thanks for the video. I found it interesting and entertaining. I do agree that numbers are descriptions. Numbers refer to something other than themselves.

Where I disagree is the claim that they are made up. They are not made up descriptions but rather absolute descriptions. An alien might use a different "word" for two, but what ever "word" it uses is going to mean exactly the same thing as we mean when we say "two". The notion of a reality without quantities is nonsensical.
