So … what’s your alternative?

I'm not here to debate DNS.

I only explain that DNS delegation is structured with a central `.` zone.

The central node is all-powerful. It can remove any name by removing the top level delegation for that name.

Try running a root server like I do for myself. You will reevaluate what you have just said by then.

Sure you can run your own internet too and incompatibly use the same addresses IANA assigns. Guess that proves IP addresses aren't centrally allocated.
