Either way, those need to go as it hurts the league.
I am far from an expert on law, but some broader concerns on the buyout clause law:
The problem with integration of any kind is that you cannot afford local legal frameworks go against the overarching framework. EU regulations for example are supposed to supersede and override the national-level law, otherwise integration could not work.
When the Boshman law was introduced it brought a lot of hardship to smaller clubs and it depleted home-grown talent but its uniform application within EU member states ensured that there are no exceptions and asymmetrical developments. In other words, in its harshness, it was fair because, even though it depleted less powerful economically clubs and clubs from modest leagues, it did so evenly.
What's the issue with the release clauses? If there is not a common overarching framework, enforced by UEFA, then the way they are implemented and included in the players' contacts will lead to different standards in the transfer market. How 'fair' is it in a common integrated transfer market to have players that their clubs have the privilege to 'refuse to sell at any price', like PSG-Veratti or Leipzig-Keita, and at the same time have Barca being obliged to include a buy-out clause in Neymar's contract and of determinate amount as well.
It seems to me that the clause issue should be centrally regulated and should be a part of FFP as well..
This multiple standard situation is totally against the already formed integrated common transfer market.
