The problem is that DNS powers the internet as we know it, getting everything ever to switch over is at least another 30 years after you make a protocol (that would also need to have literally no downsides).
Just look how quickly DoH is being rolled out, or Google's QUIC.
Realistically if Google, Mozilla, Cloudflare, Apple, Microsoft, and a few others agree that this move is bad, and wanted to stand up a new .org TLD...they could, and I don't believe it'd be illegal (IANAL).
