I think the point of bazball is to always try and put the opponent on the back foot.
If they set a trap for you by sticking men on the boundary and bowling short, I think they have the mindset of, well I'm just gonna tonk these short balls for 6 and put the oppo on the back foot, forcing them to change tactics, not the other way around.
Have a positive and attacking mindset when facing every ball and don't worry about getting out is a big part of bazball, you can't have this middle ground of selective bazball, it's all or nothing and I for one love it.
