A walk is an inherent part of the game.
The proposals mess with the game's fabric a lot more than other rule changes that I also despise, like extra innings man on 2nd, which feels like having money in the middle when playing Monopoly.
Slot a good hitter after guys you don't want IBBd and you won't have many IBBs.
Saying a walk is an inherent part of the game is meaningless. Watching the best hitters hit baseballs is what I enjoy about baseball. Watching pitchers figure out what pitch to throw and bamboozling those great hitters is what I enjoy. No one cares about the IBB. What are you defending? It's a valueless cowardly move that deprives you from what's really enjoyable about the game.
The man on second was a great idea to try. It was covid, they had a shortened season, they tried something different. They should have tried more things. But people don't like it, so they're switching it back.
There is nothing about the intentional walk that will change the fabric of baseball at all. It will just increase the opportunities to see the best parts of baseball - game on the line, good hitter up with the chance to win the game.
And none of these proposals even get rid of the ibb, they just make it more costly, so you have to really really not want the guy to hit.
