This is because you (in theory) need the whole blockchain to validate an NFT, so you want to keep it as small as possible.

But since you store the Cryptographic Hash of the image too, you can validate that the image on the server is actually the same one referenced by the blockchain. You could even move it to another server, but it will break the link obviously

Except you don't own that server and have no control over it, and if the server owner takes the image offline you're screwed

It does not really matter. You’ve still got the JPEG (or whatever else). Just calculate the hash and you can proof that it’s the one referenced.
