I do not accept that premise at all. You make it sound like they discovered it was wrong after the fact rather than knowing the rules before making the decision. That's some serious white washing
My intention was preventing the abuse of financial power e.g. put price controls on player acquisitions so Manchester City or PSG are not allowed to pay €100M for a new player while other clubs can't afford top players or rising stars. It would disturb the football industry at first but you can make that policy dynamic or in another words limits change as the macro climate in the football industry changes.
