i don't know if you just want to draw some doomsday scenarios.
or if you didn't read the proposal properly.

rental market?
when the bots went from modern to wild the rental prices of the wild cards were destroyed, maybe you just read the other comments i don't really feel like explaining it all again with the rating inflation. 😒
the rental market will most likely even benefit from it. a bronze player in modern rents on average ten times as much as a wild silver player. in wild the accounts no longer need cards to fight because of the strong rating inflation and the whole dead accounts. Therefore, they usually have only the most necessary to circumvent the starter cards penalty. I think you just look at it, in wild silver outside the leaderboard area play almost all only with lvl 1 cards, in modern would not even manage it in bronze 2. so that all the empty accounts disappear, the rating inflation goes down, the accounts need better cards so they have to rent more. . . .

and new players? the measure is only for wild not for modern!

and apart from the fact that your solution has already been rejected, it doesn't even make sense if i put myself in your shoes. you think if the botfarms go away the rental market will die, and your solution is that these botfarms stay there and keep renting even though they get no rewards without kyc.😂

your own thoughts contradict yourself. you should think about it again^^
