I agree. Do you have any thoughts on how to mitigate this? After all, its in your best advantage and the companies to hire someone with talents because of the value they can bring.

Unfortunately (at least in my opinion) the way to mitigate it is make contacts, friends, colleagues etc. Meet people, stay in touch with them. In my experience relationships are by far the most important aspect of a career. I'm not naturally someone who forms these relationships easily, but it's by far the most valuable and important thing I've done in terms of the jobs I've had.

Not really, except having a lot of experience on board from the start.

Which will also naturally attract more of the same.
