The reason is because the cartel needs to gradually consume the hashrate of the network, so it can delay the transactions of non-cartel customers who are on the blockchain. To force them to join the cartel or lose customers to the cartel.
Yes, much hand waving. Again, just because you can say it, does not make it so. There is zero evidence that a cartel of any size less than 51% of the total network can delay fee paying transactions issued by others to any noticible extent.
Your ignorance of Satoshi's white paper and Bitcoin 101 stands out like a blackeye.
The percentage of the hashrate controls the percentage of blocks won, which therefor controls the percentage blocks that the cartel can exclude non-cartel transactions.
Now shutup mofo.
