i googled this and dont know why there arent a billion of these suits every day
Probably because the grounds are so specific. Just because your "prospective economic advance" is damaged doesn't mean it was an intentional interference of the person who damaged it.
Did the women coming out against Joey Ryan want to stop his behavior, or did they intentionally expose him to stop him from making money?
Did Impact stop working with him because they didn't want to associate with his behavior, or did they intentionally break the contract to stop him from making money?
Even if the result is there it's hard to prove the intentional interference (which is also different from breaching a contract for a valid reason, such as a breach of code of conduct).
