You’re asking for specifics on their concerns while not providing the specifics that were already in place in your claim here.
If you want to change something, the very least that's expected of you is that the change actually fixes something.
If you can't even put together a description of exactly what's broken, obviously you can't tell if your proposal is even able to fix anything.
And may I point out the fact that this very discussion starts by admitting that alternatives are not effective?
Change for the sake of change is a pointless endeavour. Moreso if it comes from mindless militancy.
