Football can never read. There’s always some fountain of cash. Nobody in Europe will stop it.
This is what will happen. Saudi will just start buying up players and distorting the market. It makes no sense for older / tier 2 players to turn down those wages. Once they have a strong base, they’ll be able to throw their weight around. You’ll see shifts like club World Cup, potentially super league etc., either involving Saudi teams or being owned by Saudi. They will hit a tipping point when only the Qatari/ Emirates owned clubs can compete with them
