Thanks for taking time to elaborate and sorry if I sounded rude. It's just that along with the ironic "scroll down" suggestion, I was afraid I'd be called "fun at parties" by taking you seriously (sorry it happens pretty often on social media so I'm just being wary). But now I can see where you're coming from.
That said, while you personally believe that the game design should always place considerations about NT and U21 far below managers' own teams, you won't be able to change the fact that there have been changes in the past involving NTs in the past (I think one of them involved NTs and free agency). While removing the NT feature won't affect most of the users in BB, but it's a fact that NTs affect a number of things on the level of "personal teams" like merchandise and sale price. So as much as you dislike it, the what happens at NT level can still be taken into account and it's definitely not going to be shelved like the All Star Week.
Continually fiddling with extra taxes, or listing fees, or whatever isn't going to do squat to address them.
You weren't here long enough to know this, but quite some years ago, it was possible to transfer list players right after purchasing them, and day trading was pretty rampant. To address this (yes BB actually took action against flipping approaches), the game devs prevented players from being listed for 4 days after they got purchased. While it didn't entirely curb day trading, but it did make day trading less profitable. Same thing applies here - I'm not looking to completely prevent people from relisting their players or fish for absurd prices, but to make it so that the impact is smaller.
So not only is there a precedence where BBs actually took action against flipping, they put a restriction to it, and it worked. So what basis do you have for your claim?
