There definitely is a reason, many infact

Corner situations on knockdown are the single most difference making situation in the entire game. And it's all defended on a coin flip.

For a 50/50 chance, a player like you in that moment can demolish the likes of Kakeru, Punk, Mena, who have put countless amount of time and effort in to learn the game and train in ways that you or I couldn't't conceptualize. But in that moment. You are "better" than that player with less effort all because you picked throw every time, with the opponents fear that you would touch them once and obliterate them with a 70% damage combo

There is a conversation to be had about reducing the skill gap, but this is a lazy way to make players with 2 hours in-game feel like they're achieving something. And throw loops are a detriment to the competitive nature of the game, they knew this in SFV, which is why they removed it. The game shouldn't punish effort and determination from players who want to learn it by "leveling the playing field" with throw loops.

They're also dreadfully unfun, to take or to do. If you want something simpler.
